[R] subsetting data file by intoducing a second file

Hello,

Read the help page ?subset more carefully, it's argument 'select'
you
should be using:

subset(bg, select = c_bg)


Hope this helps,

[R] subsetting data file by intoducing a second file

Hi Ozgul,
the interesting part is the "select" parameter in subset:

subset(bg,select=c_bg[,1])


cheers
