In python, one can do this mydict = dict([(keyfun(x), valfun(x)) for x in mylist]) to create a dictionary with whatever keys and values we want from an input list of arbitrary size. In R, I want to similarly create a list with names/values that are generated by some keyfun and valfun (assuming that keyfun is guaranteed to return something suitable as a name). How can I do this?

Dear Colleagues, I have a data set that looks as below. I'd like to count the number of dates in a series of arbitrary ranges (breaks) i.e. not pre-defined breaks such as months, quarters or years. table(format()) produces ideally formatted output, but table() does not appear to accept arbitrary ranges. I also tried converting the dates to numeric and using histogram to try to get the data,

Hello! How can I do a factor analysis backwards to get an arbitrary covarianz matrix out of an arbitrary number of generated random variables that have a correlation near zero. Or the same question shorter: How to generate random variables that have a spezial correlation pattern. I would like to be able to do this to generate arbitrary data structures for simulation purpose sincerely stefan

Dear R users, I'm wondering how I can generate an arbitrary number of loops in R. For instance, I can generate two "for" loops to get ICC among any two-way combination among 10 variables. Here is the code n<-10 for (i in 1:(n-1)) { for (j in (i+1):n) { icc(cbind(DATA[,i],DATA[,j])) } } If I need three-way combination, then a code with three "for" loops will be:

Hi, I'd like to terminate IAX call on PRI interface. What conditions should be met to be able to send arbitrary caller numbers to called party, so he can call back to supplied ISDN number (that is different for every IAX user) - not through PRI interface, but plain ISDN call !! Thanks in advance, regards, Rob.

Hello. Is there an easy-to-use contour plot function analogous to scatterplot3d that can draw handle a dataset of arbitrary (x,y,z) triplets? That is, say x, y, and z are each measured quanties, and exhibit neither order nor regularity. I looked at the lattice package function "contourplot" but it seems complicated, and it's not clear from the documentation whether it can

Dear R-help, First of all, thank you VERY much for any help you have time to offer. I greatly appreciate it. I would like to write a function that, given an arbitrary number of factors from a data frame, tabulates the number of occurrences of each unique combination of the factors. Cleary, this works: > table(horse,date,surface) <SNIP> , , surface = TURF

Hello folks, Any ideas how to do this? data.frame is a data frame with column names "x1",...,"xn" y is a response variable of length dim(data.frame)[1] I want to write a function function(y, data.frame){ lm(y~x1+...+xn) } This would be easy if n was always the same. If n is arbitrary how could I feed the x1+...+xn terms into lm(response~terms)? Thanks Richard -- Dr.

Mike Williams contributed a patch to support arbitrary comparisons. This is now in the trunk and will be part of the next release. So you will now be able to do this: result.should_be < 5 result.should_be >= 7 It also supports alternate syntax for should_be, should_match result.should == 3 result.should =~ /regex/ Personally, I prefer should_be and should_match in these cases, as I think

Hello! I have something like this: test1 <- data.frame(intx=c(4,3,1,1,2,2,3), status=c(1,1,1,0,1,1,0), x1=c(0,2,1,1,1,0,0), x2=c(1,1,0,0,2,2,0), sex=c(0,0,0,0,1,1,1)) and I can easily fit a cox model: library(survival) coxph(Surv(intx,status) ~ x1 + x2 + strata(sex),test1) However, I want to

Hi all, Is it possible to specify an arbitrary unix directory to be mounted from samba? For example, to mount /usr/local/bin ? Using a different smb server, I've seen the ability to do this by doing something like Connect to: \\smbserver\/usr/local/bin Connect as: user Password: **** In other words, I'd like to be able to specify the exact path I'd like to mount without having

I have a data file that looks like this class pigeon falcon propeller jet wing fly birds 25 37 0 0 2 1 planes 0 1 28 40 1 3 birds 19 41 0 1 4 6 planes 0 0 25 50 5 5 planes 1 0

Is there a reason why AM:S doesn''t support arbitrary keys to serialization? I can see a lot of uses cases where arbitrary keys could come handy. Right now, if one tries to do it, AM:S checks if the keys match a method of the model and raises exception if it can''t find any. class Client < ActiveRecordBase attr_accessible :name, :address, as: :creator include

Hello: I have been able to successfully add a profiling pass to my PassManager. I now want to dump this profile information arbitrary (like maybe after 1 second of running the program). The problem is that the profile functions are in a separate library which is loaded dynamically. I cannot call: EdgeProfAtExitHandler(); directly because of linker problems (EdgeProfAtExitHandler() is

Can anyone suggest a simple way to calculate a 'hash code' from an arbitrary R object? hash(x) should return an integer or string with the property that if hash(x) != hash(y) then x and y are not identical and the time to compute hash(x) should be quite short. Any suggestions welcome thanks Adrian Baddeley

Hi Mihamina, Indeed I'm looking for the same thing. I've looked at CMML/Annodex which looks very promising for what it is, but total overkill (and overly complex) to simply add meta-data (comments) to arbitrary ogg/theora/vorbis/speex (does speex have different comments then vorbis?) Does anyone have any simple C code that can just retreive and set arbitrary meta-comments in

Hi. I am beginning to learn LLVM (using LLVM 2.3.0 on a Linux x86_64 machine) and wanted to check the status of the support of arbitrary size integers. To do so, I tried to modify the HowToUseJIT example by replacing the Int32Ty with another size (let's say 12 bits for the example). While it compiles ok, I get the following assert at run-time: HowToUseJIT: LegalizeDAG.cpp:4059:

Hello, I wanted to ask one general question ( for now it is hard to check it manually, maybe there is a fast answer): can I construct an operation, say, addition, from operand_0 - 5 bits size and operand_1 - 3 bit size -> receive result as 6 bit size . I am basically reducing these sizes in the whole IR, so I want that all operands can have arbitrary sizes ( llvm pass is not really good because

...erent colors. "PM10" however, displays all classes in one color when there should now be two. Additionally, I now obtain a panel entitled "Ultrafines" which I'd like to suppress. The actual data set has a number of different pollutants, so what I'd ideally like to do is arbitrarily define two panels with different grouping variables. I've tried to set up dummy groups and to condition on those, but with no luck. I think what I need to do is possible with viewports, but is there no way to entice lattice to function in this way? Any help would be appreciated. cheers, A...
