[R] Reading complicated data file

[Don MacQueen]

Something like

tmpdat <- scan('filename',what=list(id=0,col1='',col2=''))
use <- tmpdat$id==1
dat <- data.frame(x=as.numeric(tmpdat$col1[use]),
                   y=as.numeric(tmpdat$col2[use])

should get you a dataframe with two columns corresponding to the
second and third values from each row. (caveat: I haven't tested it. 
Check the documentation for scan regarding delimiters. Also, I'm 
assuming every row in your data is complete, with exactly three 
values.)
