filtering samples

Hi all,

I do have list of samples as a txt file and want to only keep these samples from this large file; column name is samples name in the large file.

> col <- read.table("samples.csv", sep=",", header=FALSE)
> head(col)
      V1
1 DC103R
2 DC110R
3  DC115
4 DC120R
5 DC122R
6  DC124



count <- read.table("betas_1.csv", header=T, sep=",", as.is=T, na.strings="NA")
count[1:5,1:5]

                DC103R     DC110R      DC115      DC120R       DC122R
