Create a frequency histogram for codes

Description

Create a frequency histogram for codes

Usage

code_freq_hist(
  x,
  codes = ".*",
  sortByFreq = "decreasing",
  forceRootStripping = FALSE,
  trimSourceIdentifiers = 20,
  ggplot2Theme = ggplot2::theme(legend.position = "bottom"),
  silent = rock::opts$get("silent")
)

Arguments

x	A parsed source(s) object.
codes	A regular expression to select codes to include.
sortByFreq	Whether to sort by frequency decreasingly (decreasing, the default), increasingly (increasing), or alphabetically (NULL).
forceRootStripping	Force the stripping of roots, even if they are different.
trimSourceIdentifiers	If not NULL, the number of character to trim the source identifiers to.
ggplot2Theme	Can be used to specify theme elements for the plot.
silent	Whether to be chatty or silent.

Examples

### Get path to example source
examplePath <-
  system.file("extdata", package="rock");

### Get a path to one example file
exampleFile <-
  file.path(examplePath, "example-1.rock");

### Load example source
loadedExample <- rock::parse_source(exampleFile);

### Show code frequencies
code_freq_hist(loadedExample);
