Without knowing your OS, there is no way anyone can tell you. And you
probably want to know 'cores' rather than CPUs. And for some specific
OSes, you will find answers in the archives.
Beware that this is not a well-defined question: are these
physical or virtual cores?, and having them in the system and being
allowed to use them are different questions.
Package 'multicore' is one that attempts to do this in its function
detectCores (see the source code). And on Sparc Solaris it is pretty
useless as it gives virtual CPUs, 8x the number of real CPUs.

Dear List
Sorry if this question seems very basic.
Is there a function to pro grammatically find number of processors in
my system _ I want to pass this as a parameter to snow in some serial
code to parallel code functions
