similar to: eval function with javascript-semantics possible in R?

Dear r-helpers, why do I get an output in the first iteration of the for-loop which contains the string values of the input vector, and how can I avoid that? Here's the output (only line 1 is wrong) latentVariable Indiv Group 1 rPlanning rIterat rTDD 2 rPlanning 0.79 0.84 3 rIterat 0.79 0.83 4 rTDD 0.9 0.96 5 rStandup 0.83 0.82 6

Dear r-helpers, I am getting a mismatch error between two variables: svp <- ksvm(x, y, type="nu-svc") Error in .local(x, ...) : x and y don't match. and I suspect that it might be due to missing index in the y variable which I defined as: y <- (LVvar[,1]) I tried various methods to make the y assignment in the same format as x, which is a dataframe x <-

Hello guys, I''m a scriptaculous newbie (I started working with it only yesterday) and I have already the first problem. I''m trying to implement a drag & drop list (fallowing the shopping cart example http://demo.script.aculo.us/shop) and I''m almost done but after dropping an item on the target div I need to refresh the page to see that the item has been moved.

Dear R-helpers, my little function below calculates the group score (tmpGroupMean) of an item, appends a "_mean" on its name and stores its value on this name. However, it does not calculate the mean of these scores (LVMean) in the same row correctly, as you can see in the below output which strangely also contains NAs. What is wrong?? Thanks for any hint!!! ###### ## start

I''m trying my best to get Builder to give me a nested representation of my nested database tables, but I think I''m not getting any closer to a solution. In fact, now I''m in Syntax Error land, rapidly approaching Missed Deadline country. Perhaps you could be the one to save my ass? Basically, I have Images which have many Options (intended to represent

I'm having trouble setting up the function call to handle two lists of matrices. Each list has 6 matrices - Each matrix is 20x10. I need to do some basic math on corresponding matrices in each list. Here are some outputs of these lists, etc... # first list > length(qc.pm) [1] 6 > dim(qc.pm[[1]]) [1] 20 10 > qc.pm[[1]][1:4,1:4] 441-JP071707.CEL 442-JP071707.CEL

Dear all, I know this topic has already been covered in other posts (at least the for loop Vs apply family of function), but I am looking for fresh / up-to-date opinion and feedback on those 3 methods to run unavoidable loops in R. I realise that it may be too general question for many, so any feedback appreciated. 1. apply Vs for loop >> Seems apply is (was?) supposed to be faster than

From: Paul Emmerich <p.emmerich at first-colo.net> Hi, the new API for initramfs and files in master lacked the ability to build initramfs objects from files loaded via HTTP/TFTP in Lua. The documentation indicated that it should be possible (and I believe I did that in an older version). I implemented a few new functions to handle files/initramfs objects better. Changes: * NEW:

Hi all, Sorry if this is documented somewhere, but trying to search and google for ways to alter my "..." argument is having me chasing my tail. Is there someway that I can manipulate the elements in "..."? Specifically I'd like to use certain vars in "...", then remove them from "..." and pass the rest of "..." to another function.

Hi all, the language reference for the alloca instruction states: The ‘alloca‘ instruction allocates memory on the stack frame of the currently executing function, to be automatically released when this function returns to its caller. when using come c code like void myfunc(void){ int i=4; double d[i]; } the ir shows enclosing llvm.stackSave & restore constructs, enclosing the alloca

> In C, the ‘minimal’ part is called the ‘scope’. Variables are always destroyed in the inverse order to the order in which they are created and so it’s always trivial to translate each into a stack save followed by an alloca when the variable comes into scope and a stack restore when the variable goes out of scope. > >> what would happen if stack safe/remove would be neglected?

I sent this to the author of geoip a few days ago and haven''t heard back, yet. Since he may be on vacation or busy, somebody may also hit this problem in the mean time, I figured I''d post the patch + git repo I sent him here. Unicorn users: The pread(2)/pwrite(2) syscalls are very useful for making libraries like this one (that rely on an on-disk database) compatible with

Hey guys, I recently published an article documenting some of the more useful and interesting parts of Prototype''s Enumerable, Hash and Array objects. You can find it here: http://encytemedia.com/blog/articles/ 2005/12/07/prototype-meets-ruby-a-look-at-enumerable-array-and-hash If you have any feedback or suggestions, fire away. Cheers, -Justin Palmer

By emitting a stack save and restore for d, clang doesn’t need to have different IR generating code for your example and for this one: > > void myfunc(void >

This must be FAQ, but I can't find it in archives or with a site search. I am trying to construct a frequency table. I guess this should be done with table. Or perhaps factor and split. Or prop.table. cut? findInterval? Argh! Please correct me if what I am looking for is not called a "frequency table". Perhaps it's called grouped data. > zz$x9 [1] 65 70 85 65 65 65 62 55

How does one create a vector whose contents is the list of variables in a dataframe pertaining to a particular pattern? This is so simple but I cannot find a straightforward answer. I want to be able to pass the contents of that list to a "for" loop. So let us assume that one has a dataframe whose name is Data. And let us assume one had the height of a group of people measured at
