Dear all,

a related follow up -- with the hope for some feedback from the specialists. Is the following general advice justified:



If one has not more than 4GB RAM and one wants to run primarily R on one's Linux machine, it is a good idea to install the 32bit version of the operating system.
The reasons are:
The machine has 4GB RAM which implies that the 32bit version can (theoretically) use the whole available memory address space. The advantage of addressing more memory using 64bit is in this instance of a 4GB computer lost. Furthermore, 64bit often runs slower than 32bit (see Section 8 of R Admin Manual) due to the larger pointer size.

Thanks,
Roland
