Profiling for R Scripts

Description Usage Arguments Details Value Author(s)

This script will benchmark the running time of the given input file. Time used by functions defined in timed_fun data frame will be subtracted from total running time. This benchmarking tools differs to other benchmarking tools in that it times the running time of longer R scripts in a defined environment by allowing (version)control over input data, used packages and scriptfile.

1	benchmarkSource(file, timed_fun, runs, loc.src, uses_packrat, bench_log, warn_log)

`file`	R script to benchmark
`timed_fun`	a data frame whith 4 columns. Column 1: function; column 2: package; column 3: process category eg. READ/WRITE but never BENCHMARK; column 4: function type, currently only 'IO'.
`runs`	(integer) number of pre-runs which are not timed but serve to measure warm running time of the last run.
`loc.src`	chracter vector containing location of CRAN like repository which contains the source code (package_version.tar.gz) of used package versions
`uses_packrat`	use if you have packified your script using packrat. Default is TRUE
`bench_log`	filename to use to store message/warning/errors. Default is "benchmark.log"
`warn_log`	level of logging to use (choose from -1, "INFO", "WARN", "STOP". Default value is -1.
