Creating Binary Outcomes from a continuous variable
...earched the archives and my R books and cannot find a method to transform a continuous variable into a binary variable. For example, I have test score data along a continuous scale. I want to create a new variable in my dataset that is 1=above a cutpoint (or passed the test) and 0=otherwise. My instinct tells me that this will require a combination of the transform command along with a conditional selection. Any help is much appreciated. Thanks, Harold [[alternative HTML version deleted]]

MVC and Pagination
Just wondering how to best integrate with pagination and still stick to MVC... Say I have a Post model that has a published attribute. I want to show all the recent published posts on a page. My first instinct is to create a method in the Post model called recent that does the find with proper conditions and order, but the problem I have is how do I use that with pagination (which definitely does not belong in model)? Any ideas? Thanks, Chris

Running R Script on a Sequence of Files
...What I want to do is: 1) Create a list of the file names in the directory (this is really what I need help with) 2) For each item in the list... a) open the file with read.table b) perform some analysis c) append some results to an array or save them to another file 3) Next File My initial instinct is to use Python to rename all the files with numbers 1:900 and then read them all, but the file names contain some information that I would like to keep intact and having to keep a separate database of original names and numbers seems inefficient. Is there a way to have R read all the fil...

db vs filesystem

Why do non-lvds monitors default to dithering these days?
...can try and find a way to set the connector property more permanently (if anyone has suggestions besides sticking an xrandr command in my .xinitrc please let me know), but i don't see why we would need to assume that anything but lvds and eDP needs to be dithered. -- Far away from the primal instinct, the song seems to fade away, the river get wider between your thoughts and the things we do and say.

Scripting issues
Users, I am currently running scripts on a rather large dataset. Many times I sort the data into smaller datasets and must analyze them individually. My instincts are to make a for loop, but I can't seem to find a way to index each sub-dataset (data frames as the case would have it). I would make an array, however, the data types of the columns are different and as I understand, an array cannot handle this type of structure. Any advice on how to do thi...

Spedd: R vs S-plus
...d with R for Linux when doing much the same thing. I don't have a direct comparison, because they're not running on the same machine; but machine W has a faster CPU and more RAM than machine L, yet S-plus on W seems to take longer by quite a big factor (of the order of 5x) than R on L. My instincts say that "WIndows" is probably a significant factor in the comnparison, but still ... Ideally, to compare R with S-plus, one should look at them both on the same OS (Unix or Windows) on the same machine. Can anyone give me clean comparative speeds? With thanks, Ted. ----------------...

difftimes; histogram; memory problems
...16,000. Really, what I need is a histogram of all the values in this matrix. Ex): Condition1 <- data.frame('dates' = rep(c('2001-02-10','1998-03-14'),6000)) Condition2 <- data.frame('dates' = rep(c('2003-07-06','2007-03-11'),8000)) First, my instinct is to try and vectorize the operation. I tried this by expanding each vector into a matrix of repeated vectors (I'd then just subtract the two). I got the following error: > expandedCondition1 <- matrix(rep(Condition1[[1]], nrow(Condition2)), byrow=TRUE, ncol=nrow(Condition1)) Error: c...

[LLVMdev] Clarification between <type> and <ty> for alloca instruction

I've obviously being playing with C++ too long because my instinct immediately told me that dynamically sized arrays on the stack are't allowed but apparently that's fine for C99 (g++ also seems fine with this is you don't specify -pedantic) > Of course, if NumElements *does* overflow they're different: alloca > i32, i8 257 will allocate 1 i...

time sync issue
I am running a Samba domain controller with LDAP integration. I have at least some workstations which do not seem to be syncing the time with the DC at all. My first instinct is to simply set the time with a logon script, but of course that runs as the user, whom does not have permission to set the system time. I would prefer to get it working right, to where the system syncs its time with the time server runnong in the DC. I have tried to find the cause. net time \\dc...

[LLVMdev] Need advise on adding tests - Was: Re: ARM MC .s status?
Hi everyone, I am trying to get up to speed on the MC object file emission for ARM, the first cut being for ELF, and the testing required for that. Obviously, we want the tests for the .o emission to ultimately test the entire .ll -> many llvm passes -> .bc -> .o, but as a first cut, my instinct tells me that a simple .cpp unit tests that directly invokes the MC code to generate (and self-check) the ARM ELF might be the way to go, but I am wondering where the best place for something like this is? I.e. From what I can tell, in the test-suite, even single file .c files are (according to the...

No bootloader with D-I in domU on part. RAID1
.... There isn''t as much as a grub directory written on the /boot partition. Not very surprising, the guest OS won''t boot after finishing the installation anyway. I tried to install grub manually from outside the domU, but that also doesn''t seem to get me anywhere. Did I instinctively pick the one disk setup Xen (or grub) won''t work with?

Confidence intervals and polynomial fits
...ts. Intuitively, I would have expected the confidence limits for the quartic term to be much narrower than for, say, the linear term, because the effect of variation in the quartic term is so much larger. But the way confidence intervals are calculated in R, at least, does not seem to follow my instincts here. In other words, predicted values using the 2.5% value of the linear coefficient and the 97.5% value of the linear coefficient are really not very different, but predicted values using the 2.5% value of the quadratic coefficient and the 97.5% value of the quadratic coefficient are enormously...

Why can't "apply" be used with "as.factor" on a data.frame ?
Hi all, Let's say I have a data.frame and wants to turn each of it's columns into a factor. My instinct would be to use as.factor with apply. But this won't work, and result with a data.frame of characters. I found another solution for how to achieve this, but I would also like to understand - *WHY* does it work this way? Here is an example script: a <- data.frame(x1 = rnorm(100), x2 = sample...

[LLVMdev] addrspace attribute and intrisics
...ooked into the implementation details, at the high level, I personally think having the address space argument is cleaner than having it encoded as a pointer. The memory barrier places a barrier on the entire address space. When I see the %ptr11 on the memory barrier instruction, my first instinct is to that it is a memory barrier on the region of memory that %ptr11 points to.

Mail slowed down to a crawl...
Been moving along just fine for a couple years now, then in the last two days, email has slowed to a crawl. Retrieving email via IMAP is very slow, progress bar in the mail client shows that it is downloading messages almost constantly, like it never closes the connection, or it?s getting the messages very slowly. The server that dovecot/postfix is on has also bogged down to a crawl. The

DW_OP_implicit_pointer design/implementation in general
...out with the LLVM_implicit_value (or was it LLVM_explicit_value? I forget)) - and synthesizing artificial variables in the backend rather than trying to track which variable a pointer points to. I think this would keep the impact on optimizations smaller & would be more general. My wager/belief/instinct is that most cases won't be pointing to a named variable with a single level of indirection, but to unnamed variables, multiple levels of indirection, etc. > I get the feeling that allowing more options here will come > out as more conditions / branching elsewhere, in a way we could try...

kcc_periodic output
Either the local server is busy, or possibly (but it would not explain the samba_kcc) Samba's drepl process is stuck talking to a remote server. Is the drepl local processes very busy doing inbound replication? My instinct is either the server is very busy (and this should show up in CPU use) or a transaction is being held open excessively.
