Dear R-users,
The strsplit function does not exist in S-plus and I would like to
use it. How
could I reproduce the function in Splus or access to its source code?
Thank you

Dear R- Splus experts,
In R, I have frequently used do.call with strsplit. and I have a hard time with
Splus.. any suggestions?
for example, the R code below:
do.call(rbind,strsplit(paste(letters[1:10],c(1:10)), ))
Thanks so much,
Santosh
that gives the name of the function, so replace
do.call(rbind, ...)
with
do.call(rbind, ...)

Pardon my ignorance, but why is the do.call necessary? why not just execute
the rbind function?
What's the advantage in putting it in a do.call wrapper?

I've thought a bit more about this problem, and recall that I originally
wrote Strsplit() [and replacements for sub() and gsub(), which were not then

because other functions in the package

nothing is ever wrong if seen from an appropriate perspective. for
example, there is nothing wrong in that many core functions in r deparse
some, but not all, of the argument
R does not support tail recursion so not using it would
not matter.

this is a feature, i guess.
another issue is that the recursive calls receive substrings as
arguments, which means copying the whole remaining content, and the
copies would not be deallocated
