Hi,
I perform the operations unlist,strsplit,gsub and the for loop on a lot of
strings and its heavily slowing down the overall system. Is there some way
for me to speeden up these operations..maybe like alternate versions that
exist which use multiprocessors etc.

Hi,
first off, I wanna ask how do I declare a data.frame of 0 rows and n
columns?
Coming to my problem,
I have a data.frame of 22 columns by dynamic rows which I insert using
rbind. The total number of rows could go upto 2,00,000. The problem is that
after about 800 or 900 get inserted rbind sta
great! Thanks

Hi,
I built a package in linux and would like to use it in windows. I cant build
the package again in windows because it would miss the necessary libraries
etc(I'm using Rcpp). So I need to generate a binary version and try to
install it in windows. I tried this and I get the error

Awesome. Thats exactly what I want.
