So it seems the problem is the linefeed (0a) absent in the second
file, probably generated by some evil excel or something like this.
My question is: is there any simple way to make read.table robust to
deal with this problem? I would like to avoid solutions such as
re-implement using scan or asking the user to deal with this for me,
changing himself the file.
Did the line get read?
(I have failed in my efforts on a Mac to create a file with a text
editor that throws that warning.) In a sense it appears to already be
"robust" , since it only generated a warning, rather than an error. If
you want to programmatically turn off warnings, then:
?warnings
?options # with a bunch of settings for warn
Perhaps inside your function you could call set warn = -1 the restore
to =0 before exit.
options(warn=-1)
read.table( ... )
options(warn=0)
Thanks in advance
