Hi,
If it is to get the first 18 genes (based on rownumbers)
dat1<- read.table("apcall.txt",header=TRUE,sep="",stringsAsFactors=FALSE)
dat1[1:18,]
#or
dat1[as.numeric(rownames(dat1))<19,]
A.K.
>The row numbers represent 7129 different genes
>The 38 columns represent 38 different patients
>How can I find the genes with A number < 19 in these 7129 genes?
>I have searched and tried for 7 hours but still can not find the way to solve
apcall.txt
