Dear all, I'm new to this list, so let me greet everyone. My problem is that I have several thousand data files which I want to perform a lot of R commands on, which are found in a seperate .R script. Now, what I did was within the R prompt, I used to read in a list of the data files. e.g. namelist <- readLines("list_of_names",n=-1) for (i in 1:100) { k <-

Hi, I''m using CountryCodes to get countries list for select box. It provides self.countries_for_select(*args) method exactly for this purpose. I''m using it in only one place in my view. So I was thinking about caching this data somehow, so it won''t have to be recreated every time the page is loaded. The problem is that the plugin initializes its main @countries

Hello... I would like to use R for 'pipelining' data among several programs. I'm wondering how I can use R to call another program, feed that program a set of parameters, and retrieve the output. E.g., I have an executable that, when opened, prompts the user to enter a set of parameters. The program then executes & prompts the user for the name of an output file. I need to

Hi, I got very small app that has user part and admin part. The problem is that after a while the sessions table has ~150mb. I don''t really need to store any user data in the session for the user part. I only need it for the admin part. Can I simply turn session off in controllers from the user part? Are there any drawbacks of turning the session off? Regards

Hi, I am trying to figure a way to allocate a string SEXP so that gc() won't ever collect it. Here is a little bit of a background. Suppose I want to write a .Call-callable function that upon each call returns the same value, say mkChar("foo"): SEXP getFoo() { return mkChar("foo"); } The above implementation doesn't take advantage of the fact that

The release schedule has now been set with a release date on April 18. The detailed procedure can be found at http://developer.r-project.org/ (it is not quite there yet, but will appear after a short propagation delay.) The main point for non-developers is that we start making alpha tarballs on March 21 and beta tarballs on April 4. Only very simple and/or critical bugs are fixed in the last

Hi, for presentation purposes I would like to clear to whole console window (like in a UNIX terminal: 'clear'). Is there such a function? If not, I could image that is not too hard to write such a function. Cheers, Hans

Hello, This code works fine but is so fast I can't see anything but the last plot. for (i in nrow(X)){ plot(as.numeric(d[i,])) } I'd like to view a plot every 500 milliseconds, nrow(X) = 400. How?

Dear all, I would like to start a process from an R program in such a way that I can both feed input into the process and read the process's output. It seems that in R, I can have a pipe for writing into another process's input or a pipe for reading from another process's output, but not both. Doing both necessitates forking, such that the child can start the external process and

How precise is R numerically? For example I wrote the following function for calculating the volume of the ball inscribed in the unit cube in m dimensions. In order to see what happens in 40 dimensions, I created an output of 24 digits. But how many are precise? Thanks Josef Eschgf?ller Ferrara --------------------------------------- Vol = function (m) {if (m<=1) 1 else Vol(m-2)*pi/(m+m)}

I have been using the fork package on a cluster to spawn jobs. I have noticed that I end up with many "R defunct" (zombie) processes following the use of fork that do not die completely until I close down R. Initially, I thought it may be my code but I ran the example from the latest fork package (see code below) on R.2.3.1 and ended up with the same problem. The code from the

Hi, I am using the following command to print to a file (I omitted the file details): cat( paste( paste(orientation, start, end, names,"\n"), paste(start, end, "exon\n"), sep="")) where "orientation" and "names" are character vectors and "start" and "end" are integer vectors. The problem is that R coerce the integer vectors
