parameterFrequency

Plot of histogram of parameter values

Description

parameterFrequency plots the frequency of the parameters values in a set of target algorithm configurations. It generates plots showing the frequency of parameter values for each parameter, with rows * cols parameters being shown per plot. If a filename is provided the plots are saved in one or more files.

Usage

parameterFrequency(configurations, parameters, rows = 4, cols = 3,
  filename = NULL, pdf.width = 12, col = "gray")

Arguments

`configurations`	(`data.frame`) Parameter configurations of the target algorithm (one per row).
`parameters`	(`list()`) Data structure containing the parameter space definition. The data structure has to similar to the one returned by the function `readParameters`.
`rows`	Number of plots per column.
`cols`	Number of plots per row.
`filename`	Filename prefix to generate the plots. If `NULL` the plot displayed but not saved.
`pdf.width`	Width for the pdf file generated.
`col`	Color of the bar plot.
