Hello, I'm trying to paste two columns of a matrix GB_ACC GENE GENE_SYMBOL NM_010657 NM_010657 NM_027162 NM_027162 NM_198863 NM_198863 NM_010727 NM_010727 These two column are a part of a 41,000 x 26 matrix. 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

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

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

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

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 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

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",

Hello, I was wondering whether there is a possobility to add File types to the list of filters known by R. I'm using the function choose.files in Windows. I have some files I always use and i would like to filter my option to these kind of files. I have some "atr", "cdt", "gct", "gmt" etc. Is there a way of telling R to filter only these files?

Hi everybody, I am having a problem building a ROC curve with my data using the ROCR package. I have 10 lists of proteins such as attached (proteinlist.xls). each of the lists was calculated with a different p-value. The goal is to find the optimal p-value for the highest number of true positives as well as lowaest number of false positives. As far as I understood the explanations from the

Dear Duncan, Following your advice (Thank you for it) I did include into the vignettes params: configuration: !r get(data(sample_analysis)) data: !r get(data(skylineconfig)) And everything seemed (see below) to work fine. devtools::build_vignettes() builds the vignettes. Runs with NO error. By this the .Rmd file, html file and corresponding .R files is being placed into the inst/doc
