另外，从上手角度来考虑，哪个软件最容易上手？ eviews？spss？

learn R, is free and you can do any analysis you need

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
