Questions about R

Good morning. I am interested in downloading R.  I would appreciate if you
can help me with the following questions, please.

1.       Is R free, or I have to pay for support/maintenance, or it depends
on the version? Is there a paid version?

Yes, it is free, although there are commercial versions of R available, if you decide that you do need/want commercial support.

Some additional info on commercial versions here:

None of this has any effect on your ability to use R in a commercial setting, though there are some CRAN packages that do have such limitations:

2.       How safe is it to work with data using R? Is there any risk that
someone else can have access to the information?

That is outside of the scope of R and is dependent upon the security of the computer system(s) and possibly networks, upon and over which R is running and where your data is stored and managed.

Regards,

Marc Schwartz

Thanks in advance for your attention and for any help you can provide me.
