So you decided to cut down on your Statistical software expenses and decided to get R.
but the problem is you know SAS /SPSS and you need to learn R fast enough to justify switching over …….
the ideal book for you is http://oit.utk.edu/scc/RforSAS&SPSSusers.pdf
Thanks to the guys who pointed me here. Its a really easy book, you have the SAS Syntax, the corresponding SPSS Syntax and the R Syntax.
That’s useful for learners in R who got projects to execute, and need to learn either SPSS or R or even switch from SPSS to SAS.
