Hi, maybe someone can help me with this: I have a matrix of genes and values: GeneName Value Abc1 10 Abc2 11 Bbc1 -5 Bbc31 2 Ccd 5 Ccd -2 Ccd 7 Dda 5 Dda 10 ..... ..... Zzz3 -1 I would like to

Hi, Let's say that I have a set of column names that begin with the string "Xyz". How do I extract these specific columns? I tried to do the following: dataframe1[,grep("Xyz",colnames(dataframe1))] But it does not work. What is wrong with my expression?

Hi together, after I read "very often" without even a tiny bit of a contradiction, I start to have the feeling I have a basic misunderstanding of rsync. Assume one want to get a list of files which would have been transfered by rsync if rsync was requested to sync directories X and Y and one does <code> X=`mktemp` echo "abc" > $X/1 echo "abc1" > $X/2

Hi. I aim to provide pop3 and imap services to a few users. At the moment I only offer imap for squirrelmail users. However, I can't login successfully for pop3. It appears to be trying to auth against PAM, rather than directly using the passwd-file. Thoughts? Thanks, Rory Config: uthenticatprotocols = pop3 imap ssl_disable = yes login = imap login = pop3 mail_extra_groups = mail auth =

Hi all, I am interested in plotting a heatmap of a set of genes. I would like the text labels of these genes to be colored red rather than black if they meet certain statistical criteria (using an if statement). I'm not sure how to change individual color labels without changing them all. Can anyone provide some insight on how to do this? Thanks in advance, Jake

Does anyone have code that will methodically process R sourcecode, turning T's into TRUE and F's into FALSE? I got bored doing this by hand, after the first 30-odd functions-- there are hundreds left to do. I don't want to simply deparse everything, because that would destroy my beautiful formatting. The reason it's not trivial, is that comment lines, quotes, and split lines need

Hi all, I just start to learn llvm. I am trying to get the operand's name of some instruction that invokes a function field of a struct. While, I found in the result that there is a sequence number attached to the function field name. Below is an example: /******source code t2.c*******/ #include <stdio.h> void F(){printf("F\n");} void E(){printf("E\n");} void

Hi, I'm new to R (and statistics) and my boss has thrown me in the deep-end with the following task: We want to evaluate the impact that sampling size has on our ability to create a robust model, or evaluate how robust the model is to sample size for the purpose of cross-validation i.e. in our current project we have collected a series of independent data at 250 locations, from which

Wayne, While testing rsync 2.6.8, I often receive broken pipe error, even though there is no network problem, between Active and Standby nodes.

Assume a C program invoked by .Call, that returns a list. Near the top of the program we allocate space for all the list elements. (It is my habit to use "xyz2" for the name of the R object and "xyz" for the pointer to its contents.) PROTECT(means2 = allocVector(REALSXP, nvar)); means = REAL(means2); PROTECT(u2 = allocVector(REALSXP, nvar)); u =

Dear R users, Inspired by previous list discussion of the glob2rxc function, I am attempting to create a new vector called TOTAL by summing all vectors whose names begin with ABC: TOTAL = sum(list = ls(pattern = glob2rx("ABC*"))) I'm running R 2.2.1 on Windows XP. Can anyone say what I'm missing? Thank you, Mark

Is it possible to translate help files? I see there are some localization options for GUI, but not for help. I think this would be really helpful for users who don't have English as their primary language. Because all the online help is created from text files, it should be not that difficult to maintain different language versions (e.g. to mark them as not valid when primary documentation in
