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, how can I change a defined factor-variable? Like adding levels, renaming existing levels or merge several levels of a factor to one level? For example; following factor-variable is given: x <- factor(c("xyz1", "abc1", "xyz2", "abc2")) How can I add the level fgh? And how can I merge "xyz1" and "xyz2" to one level? And

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

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 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

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

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 there, i an beginner of R. some one have sent me a file (extension is .Rdata). i have installed R in my computer and i just double clicked the data. then it automatically opened R programme and displayed that [previously saved workspace restored]. the following message was displayed. Type 'demo()' for some demos, 'help()' for on-line help, or'help.start()' for an

Hi all, I am using samba 3.5.8 on a linux machine. I am not able to join the domain of a windows 2003 server in ADS mode. I am getting the following error message: # /usr/local/samba/bin/net ads join -U Administrator%password -I 10.25.66.71 Failed to join domain: failed to find DC for domain ABCDOM.PQR.COM # I am not sure what the issue here. It works absolutely fine when I try to join the

I am using 'igraph' package to make some graphs of 'gene-gene interaction'. I can get a data.frame which has three columns. gene1 gene2 pvalue AGT MLR 1.2e-04 MLR 11BHSD1 1.71e-05 IFG2 11BHSD2 2.2e-07 . . . . . . . . . AGTR1 NPPA

Hello everyone! After I ran virt-resize (v1.31.28) on my disk with win2012R2 (partition table [GPT]: VFAT (100M), unknown (128M), NTFS (64G)) My VM fails to boot: black screen informing that Windows failed to start... Status: 0xc000000e Info: an unexpected error has occured. After some investigations, I realized that Windows remembers the GUID of disk it is installed to. If I execute

Hi, I would like to use xyplot to create a figure. Unfortunately, I cannot find documentation in xyplot to specify alternating the x-axis tick labels with the x-axis tick marks. I can do this with the regular R plot function as follows. #A small version of my data looks like this data<-data.frame(matrix(ncol=3,nrow=12)) data[,1]<-rep(c(1,2,3),c(4,4,4)) data[,2]<-rep(c(1,2,3,4),3)

Hi, I used GOstats to perform enrichment test on a set of genes (20). There are 7 GO terms with pvalue less than cuttoff and therefore shown in the result table. How can I get the information that which gene in the input gene set belong to which GO term of these enriched GO terms? Thanks for any comments. best, Tim [[alternative HTML version deleted]]

Dear All I am trying to replicate a numerical application (not computed on R) from an article. Using, ks.test() I computed the exact D value shown in the article but the p-values I obtain are quite different from the one shown in the article. The tests are performed on a sample of 37 values (please see "[0] DATA" below) for truncated Exponential, Pareto and truncated LogNormal

Hi! All, To find co-expressed genes from a expression matrix of dimension (9275 X 569), I used rcorr function from library(Hmisc) to calculate pearson correlation coefficient (PCC) and their corresponding p-values. From the correlation matrix (9275 X 9275) and pvalue matrix (9275 X 9275) obtained using rcorr function, I wanted to select those pairs whose PCC's are above 0.8 cut-off and then
