[R] Finding matches in 2 files
I have 2 files containing data analysed by 2 different methods. I would like to find out which genes appear in both analyses.

Maybe with 'merge', but your message is too vague (see http://www.catb.org/~esr/faqs/smart-questions.html).

Re: [R] Finding matches in 2 files
Something like: # Sample data g1-c(gene1, gene2, gene3, gene4, gene5, gene9, gene10, geneA) g2-c(gene6, gene9, gene1, gene2, gene7, gene8, gene9, gene1, gene10) df1-cbind(gene=g1, expr=runif(length(g1))) df2-cbind(gene=g2, expr=runif(length(g2))) # Merge mdf-merge(df1, df2, by=gene, sort=T) # Unique list ug-unique(mdf[,gene]) You may find the match command useful and/or the %in% opertaor.

Re: [R] Finding matches in 2 files
Is this what you want? g1-c(gene1, gene2, gene3, gene4, gene5, gene9, gene10, + geneA) g2-c(gene6, gene9, gene1, gene2, gene7, gene8, gene9, + gene1, gene10) intersect(g1,g2) [1] gene1 gene2 gene9 gene10 On 7/25/07, jenny tan [EMAIL PROTECTED] wrote: I have 2 files containing data analysed by 2 different methods.
