[R] error with source(): invalid 'times' value

[Matthieu Stigler]

ok, thanks Jim

The problem comes from length(dep)<leading, so we get negative number...
 > length(dep)
[1] 183

c(leading, length(dep) - leading)
[1]  516 -333

But 183 seems to be the right number:
$ wc -l /tmp/RFile.r
183 /tmp/RFile.r

So now need to understand what is this "dep", and why it has a bigger 
length... tried to check source code (:-)) but could not get it... any 
idea?

Thanks a lot

Matthieu
