plot.benchmark: Plot method for the 'benchmark' timings.

In benchr: High Precise Measurement of R Expressions Execution Time

Description

Displays measurement results as a scatter plot, with R expressions on X axis and execution time on Y axis. Each expression is highlighted by its own colour.

Usage

## S3 method for class 'benchmark'
plot(x, units = "auto", log = TRUE, xlab, ylab, ...)

Arguments

x	An object of class benchmark.
units	Character. The units to be used in printing the timings. The available units are nanoseconds ("ns"), microseconds ("us"), milliseconds ("ms"), seconds ("s").
log	Logical. Should times be plotted on log scale?
xlab	Character. X axis label.
ylab	Character. Y axis label.
...	Not currently used.

Details

If ggplot2 package is available, it will be used. In order to switch to default boxplot from the graphics package set option benchr.use_ggplot to FALSE: options(benchr.use_ggplot = FALSE).

  times = 1000L
)
plot(timings)
