Hi Vikas,
The following works (I'm not very good with sapply, but the for loop
is ok if your data set is not huge).
> df <- read.table("test.txt",stringsAsFactors=FALSE)
> df
V1V2 V3 V4 V5 V6 V7 V8 V9

Dear all,
I am using grep but I did not understand the problem as I am doing something
wrong.Please help me.
I am using this code-
sf=data.frame(sapply(df[],function(x) grep('\\.&\\,', df[,9])))
the thing is i have a data frame(df) like this-
10 135349467 g G 4 0
7 matches
