Monitor memory usage in R

Question

Is it possible to monitor the amount of memory that is in use or has been used by R to call a function? For example, I have an arbitrary function, e.g:

small         


        

Answer 1

One option is to use Rprof. A simple approach is this:

Rprof(tf <- "rprof.log", memory.profiling=TRUE)

[your code]

Rprof(NULL)
summaryRprof(tf)

This will give you some information on memory usage.
