Hi all,
I have encountered a problem in some emails with invisible characters
in code snippets that throw an error when pasted into the terminal
window:
Error: unexpected input in:
"star_wars_matrix<-matrix(box_office,nrow=3,byrow=TRUE,
�"
This morning, after two hours of intense frustration, I found that I
could reproduce this by typing code containing the above line into
Kwrite, the text editor I use. When I pasted the code from Kwrite, it
worked in the R terminal window. When I pasted it into a gmail message
(set to Plain Text), copied that and pasted it into the R terminal
window, I got the error. I was helping a young friend with one of
those introductory R courses, but I have had this happen with other
requests on the R help list. I thought that it was the fault of the
fancy formatting in some emails, and could grumpily blame that, but
this is worse as I can't seem to edit it out. Anybody else had this
problem? I have sent a message to Gmail help.
(1) Don't use Kwrite (whatever that is) --- use vi[m] like civilised
( :-) ) people do. It's even available for Windoze. Yes, there is
a steep learning curve, but once you've climbed it you'll never look
back. (And for what it's worth, the curve is not as steep as that for
emacs!!! :-) )
(2) The function tools::showNonASCII might be helpful to you.
Thunderbird on Ubuntu displays it ats:
"star_wars_matrix<-matrix(box_office,nrow=3,byrow=TRUE,
followed by a line feed and then a diamond with a question-mark and a closing
double-quote.
library(tools)
showNonASCII("star_wars_matrix<-matrix(box_office,nrow=3,byrow=TRUE,
+ �")
1: star_wars_matrix<-matrix(box_office,nrow=3,byrow=TRUE,

cheers,
