Figure 3. Performance of valr functions.

Figure 3.

( A) Timings were calculated by performing 10 repetitions of indicated functions on data frames preloaded in R containing 1 million random 1 kilobase x/y intervals generated using bed_random(). ( B) Timings for executing functions in BEDtools v2.25.0 or equivalent functions in valr using the same interval sets as in ( A) written to files. All BEDtools function outputs were written to /dev/null/, and were timed using GNU time. Timings for valr functions in ( B) include times for reading files using read_bed() functions and were timed using the microbenchmark package.
