Useful info from Dirk but this measures number of R Linux installations,
not users.  If 100K is an approximate number of R Linux installations,
then the likely number of Linux R users could be somewhat more.  In my
case, I have one installation and one user since only I use it but I am
sure that there are many cases with 2, 10, 100 etc users per installation.

In addition, as Dirk says, there will be a substantial number of non-Linux
users on other Unix platforms as well as Windows.

Anyone care to make a guess?  I would estimate that there are 1/2 million
actual R users but this could be out by a sd */2 at least.
