[R] scan errors

[Brahm, David]

> Is there any way to ignore the error produced when the function
scan(file="...") cannot open the file

In S, on a Unix machine, I would say
  if (.exists(file)) scan(file)
where the ".exists()" function is defined as follows:
  .exists <- function(file) unix(paste("test -r", file, "; echo $?"))=="0"
