peek {rafalib} | R Documentation |
peek at the top of a text file
Description
this returns a character vector which shows the top n lines of a file.
Note: I realized after the fact that this is essentially a duplicate
of the base R function readLines
.

peek(x, n = 2)
Arguments
x |
a filename |
n |
the number of lines to return |
