I'm having trouble with a Bioconductor package, an variable expected in an environment does not seem to be there. As part of my investigation of the problem (most likely on my end) I'd like to list the variables contained in an environment. If you have an environment loaded, lets call it "pkgEnv', how does one find what it does contain? Mark

I just downloaded R-devel and when loaded it immediately segfaults. I'm not sure how much or what sort of diagnostic info and can provide, but below is my build script, my console output, and the output of uname -r. I am currently dependent on the development version of a package, so I'd like to get R-devel up and running if possible. I am sure there is more info I can provide, but before

I have a very long list of strings. Each string actually contains multiple values separated by a semi-colon. I need to turn each string into a vector of the values delimited by the semi-colons. I know I can do this very laboriously by using loops, nchar, and substr, but it is terribly slow. Is there a basic R function that handles this situation? If not, is there perhaps a faster way to do it than

I have a very long list that I'd like to subset based on a logical value within each element. Example below. I'd like to get just those list elements for further study whose $sig.cor slot is TRUE. In this example, I'd only want element [[2]]. Should be simple, I know. How can I do this? Thanks, Mark > gene.pair.tf.lst [[1]] [[1]]$gene.pair [1] "Lgals1:Pxmp2"

I can compile RSPython without difficulty, been when I try to load it, I get the error messages below. Also below are some cryptic warnings I get on R boot (in case these are pertinent) and my sessionInfo(). Any help is appreciated.

For years I have been using options(error = recover) either in .Rprofile or from within R for debugging purposes. The functionality of this appears to have changed and I can't recover it (no pun intended) using the ?options help page. How can I get the old functionality back, particularly from within .Rprofile? A specific line entry would be appreciated. An example, the help page, and

Recently I posted to this list with a question about using the Intel 10.1 compilers in building R and one response was basically, "why in the heck would you want to do that?" The answer is that my sysadmin believes that there will be a performance boost with the Intel vs. Gnu compilers on our Linux cluster, of which I am one of many users. Wanting to be a good citizen and use my machine

I have identical R.profiles and R_HOME directories set up on both my local machine and a remote linux cluster. To keep my libraries and R install separate, I use a site-library on both machines. The first line of my .Rprofile is: '.libPaths(new= "~/R_HOME/site-library") #tell R where site-library is' Until R-2.6.0 this was working fine on both machines, but since I have been

I have a vector of gene symbols, some of which have multiple aliases. In the case of an alias, they are separated by ' \\\ '. Here is a real world example, which would represent one element of my vector: Eif4g2 /// Eif4g2-ps1 /// LOC678831 What I would like to do is input the vector into a function and output a vector with just the first alias of each element (or, if there are no aliases,

I was running some sample code from a help page tonight and wished to redirect the sample output to my Desktop under Linux (Mint-Debian 64 if it makes a different). I was surprised to find that file name expansion using the ubuquitious "~/" was not recognized, in fact it caused R to crash. Is this expected behavior? See my output below and sessionInfo(). Also, not shown, but

Just installed the latest R-patched and get the error seen at the end of the output below. Don't know what to make of this but thought I should report it. In general, when installing the latest version of R, should one use R-latest or R-patched? R-latest is stable, but one would assume that R-patched includes the latest bug fixes.

I am getting some unexpected results from some functions of igraph and it is possible that I am misinterpreting the vertex numbers. Eg., the max betweenness measure seems to be from a vertex that is not connected to a single other vertex. Below if my code snippet: require(igraph) my.graph <- graph.adjacency(adjmatrix = my.adj.matrix, mode=c("undirected")) most.between.vert <-

I'm having trouble achieving the results I want using a regular expression. I want to eliminate all characters that fall within square brackets as well as the brackets themselves, returning an "". I'm not sure if it's R's use of double slash escapes or something else that is tripping me up. If I only use one slash I get 1: '\[' is an unrecognized escape in a
