R 2.10.1 on a Mac
I read in textfiles using readLines, then I process those files, then I use R
to execute another program. Occasionally those files contain characters other
than letter / numbers / routine punctuation marks. For example, a bullet
(option-8 on a Mac) triggers the problem.
Although R can read and process those characters, the other program cannot so I
would like to identify these characters and exit gracefully with a warning.
I discovered that the following works:
any(is.na(strsplit(readLines(FILE), "")))
I am wondering whether anyone has a better approach to this problem.
