Dear listers  

I am using a system() call to my machine (OSX 10.8, R 3.0.1. 32GB memory available):

system(paste("awk 'NR==2'", file.genepop), intern = TRUE)

and when processing big files, getting numerous helpful error messages

system(paste("awk 'NR==2'", file.genepop), intern = TRUE,  ... :
  line 1 may be truncated in call to system(, intern = TRUE)

I understand what is happening, and can see the truncations, but is there any way to prevent the truncation?  Or is there a read-limit in system() [I can't see anything in the help file… but I am probably missing something]?

Many thanks
Andrew
