compareDist: compare distributions

Description

compare multiple distributions. All based on columns in a data.frame. Creates several plots based on the integers present in plot.

Usage

compareDist(
  df,
  plot = 1:4,
  bw = "SJ",
  col = catPal(ncol(df), alpha = 0.3),
  main = paste("Distributions of", deparse(substitute(df))),
  xlab = "Values",
  ylab = "Density",
  legpos1 = "topleft",
  legpos2 = NULL,
  horizontal = FALSE,
  ...
)

Value

df, invisible

Arguments

df: Data.frame with (named) columns.
plot: Integers: which graphics to plot?
Plot 1: overlaid density estimates
Plot 2: multipanel histogram
Plot 3: boxplot
Plot 4: violin plot, if package vioplot is available.
DEFAULT: 1:4
bw: Bandwidth passed to density for plot 1. DEFAULT: "SJ"
col: Color (vector). DEFAULT: catPal(ncol(df), alpha=0.3)
main: Title. DEFAULT: "Distributions of [df name]"
xlab, ylab: Axis labels for plot 1. DEFAULT: xlab="Values", ylab="Density"
legpos1, legpos2: Legend position for plot 1. DEFAULT: "topleft", NULL
horizontal: Should boxplot and vioplot (plot 3 and 4) be horizontal? DEFAULT: FALSE
...: Further arguments passed to polygon (plot 1), groupHist (plot 2) boxplot (plot 3) and vioplot::vioplot (plot 4)
