Maybe something like this:
stopifnot(tail(unlist(strsplit(slides.pdf, \\.)), 1) == txt)

Dear R users,
I want to read a file like following :
if it is a table then z - read.table(pathname, dec=., header=TRUE)
else if it's not a table (image,doc,...) then send an error or something
like that
acually I have a read.table in the beginnig of my R code, and if my data is
not a table I become in my R console : fail in scan.
So the question is how to check the nature of the file?
something like : is.table?
I don't know the function.
Thanks for any help
Adel
