graphic for the R profiler
...nerates a dot file
from the result of the R profiler. The dot file can than be used to
create a graphical display of the profiling. You can save this file in
the bin directory of your R installation and then create a graph, for
example an SVG by piping the output of the script to dot:
$ R CMD Rprof2dot Rprof.out | dot -Tsvg > test3.svg
Some example graphics are presented in the R wiki here:
