Subject: [R] Profiler for R ?
Hi,
is there such a thing as a profiler for R that informs about a) how
much processing time is used by particular functions and commands and
b) how much memory is used for creating how many objects (or types of
data structures)?
Haven't tried it; but stumbled across "Profiling()" function in the
HFWUtils package.
Starting at bottom of page 29-30 of HFWUtils package user manual:
profiling
plots tree of execution times
Description
determines how much time a function its and sub-functions (and
sub-functions thereof etc) take to run (‘profiling’). Also draws
picture of this using the interrelations of functions.
HTH,

In a way I am looking for something similar to the
java profiler (which is started by command line and provides profiling
information collected from the run of a particular program). Is there
such a tool through the R command line or RGUI ? Are there profilers
available for the Eclipse StatET or though another package or
extension?
Thanks,
Ralf
