I was trying to install R on a unix server. Because of a firewall i can't install biocLite for working with Bioconductor. With windows it wasn't a problem. I used the option '--internet2' to bypass the firewall. I don't have any idea, how to do it with unix. I tried to set my proxy >Sys.putenv("http_proxy"="http...:8080")

Hello R users, I'm trying to extract random samples from a big array I have. I have a data frame of over 40k lines and would like to produce around 50 random sample of around 200 lines each from this array. this is the matrix ID xxx_1c xxx__2c xxx__3c xxx__4c xxx__5T xxx__6T xxx__7T xxx__8T yyy_1c yyy_1c _2c 1 A_512 2.150295 2.681759 2.177138 2.142790 2.115344 2.013047

I wanted these two column to be pasted into one (the firstone, GB_ACC). I tried to do it with a for loop, but it takes ages to finish: for( i in

Hi, is it possible to merge two data frames while preserving the row names of the bigger data frame? I have two data frames which i would like to combine. While doing so I always loose the row names. When I try to append this, I get the error message, that I have non-unique names. This although I used unique command on the data frame where the double inputs supposedly are thanks for the help

Hi everybody, I would like to know whether it is possible to compare to tables for certain parameters. I have these two tables: gene table name chr start end str accession Length gen1 4 646752 646838 + MI0005806 86 gen12 2L 243035 243141 - MI0005821 106 gen3 2L 159838 159928 + MI0005813 90 gen7 2L

Hello, I have two tab-delimited files which I would like to combine. In the first one I have gene IDs (Unique) on column 1 and than various experimental results from microarray analysis (see attached files list1 ) the second arrays have the same genes IDs (more and in a different order, some are double) (see attached files list2 ) What I would like to do is to search in the second list for gene

Hello everyone, I have a matrix of over 40000 line and about 30 columns. For my analysis I would like to add another column with ascending numbers (column header should be "order", and than 1,2,3,4 ....the end of the matrix). During my analysis I reorder them ( due to merge commands by a different column). How do I add such a column in an ascending order (or descending for what it

Hello all R users, I have a problems transforming (or maybe better regrouping) a data.frame. I have a big data.frame, which I would like to sum up according to a specific column. This is an example of my matrix: ID gen 0042787 gen2 0016070 gen2 0016070 gen3 0007409 Gen1 0007409 gen3 0006511 gen2 0006417 gen3 0016070 gen4 0006511 gen4 I want to rearrange the matrix

Hi BioC user, I have a problem extracting the gene set I would like to work with.

hello everybody, I have a directory with over 3000 files with different names. I would like to make some vectors with the file names which are belong together. I'm trying to do it with a for loop in R: SF <- c("ad", "cd", "cer", "stress", "salty", "PC", "high", "transfer", "cold",

dear all, I have a problem with a masked object in a package we created here. we make a package for a workflow of internal analysis of microarray data. to create the package we used: > install.packages(pkgs="affyAnalysis", repos=NULL) > R CMD INSTALL affyAnalysis Erzeuge Verzeichnisse ...

Hello everybody, I'm trying to install a package I have built. This package contains three scripts with various functions (S3 as well as S4 classes) I run at first the package.skeleton command with: > package.skeleton("affyAnalysis", namespace=TRUE, code_files =c("defS3.R", "defS4.R", "qc.R")) affyAnalysis is the name of the supposed package and

it did help to create the separate vectors. The problem is, I would like to continue working with each vector on its own and make some further analysis. For that i need to allocate each vector in the filePatterns a unique name, which I just can't do. I'm not so great in R loops and the help over the net regards for loops in R is quite rare. I'm really thankful for every help.

Found the simpliest way of seeing I bug I encountered doing "R CMD check --use-gct": Just launch R (with --vanilla), and do this: > ?gctorture # this work > gctorture() > ?gctorture Error in gzfile(file, "rb") : can only weakly reference/finalize reference objects # this does not It seems that when gctorture() is on gzfile() doesn't work.

Dear Deepayan and dear list, I notice a small inconsistency with the command completion of the R CMD check. --no-latex is deprecated sincs R 2.12.0 and defunct since 2.13.0 but the command line completion still suggests it: cb at cbdesktop:~/r-devel$ bin/R CMD check --no-<here I hit tab> --no-clean --no-examples --no-latex --no-vignettes --no-codoc --no-install
