if i can crack other tools, then should i still choose R?

There is not other statistics software like as R even the very expensive SAS. Searching internet you will see that all the other software offer plugins to R like as, SPSS, STATISTICA STATA. Except this there are some free programs to offer RGUI like Rcommander, Rstudio etc. So decision is yours
