Full_Name: Antonio Possolo Version: 1.3.0 OS: Linux Submission from: (NULL) (192.35.44.3) If one attempts to read a character string from a file using scan, and the string comprises more than 8190 characters, then the string is truncated to this length, and no warning is issued. I've observed this both in the Linux and Win implementations of R 1.3.0. S-PLUS (v. 6.0 rel. 1 for Sun SPARC0 does not suffer from this behavior.
Yes, that's an R limitation. Why is it a problem? I think you would do better using readLines if it is a line-oriented file. AFAIK that is unlimited. It would be easy to issue a warning, quite a bit harder to remove the limit (which dates from the days when character strings were in most places limited to 8191 chars).
