Plot top and bottom percentiles of selected variables

Plots percentiles computed by percdata using ggplot2.

Usage

percplot(data, cols = NULL, group = NULL, diff = 0.1,
         part = "both", ncol = NULL, num_xaxis = "auto",
         verbose = FALSE)

Arguments

data: A data frame.
cols: Column indices or names of numeric variables.
group: Grouping column.
diff: Difference between quantile probabilities.
part: Which part to plot: "both", "bottom", or "top".
ncol: Number of columns in facet layout.
num_xaxis: How to treat numeric column names on the x-axis. "auto": use "log" if column names are numeric and evenly spaced on a log scale with a range ratio >= 1000, otherwise keep them as factor levels. "log" or "numeric": force the corresponding scale. "character", "factor", "keep", or FALSE: keep as character/factor.
verbose: Logical; if TRUE, prints timing message.

Value

A ggplot object.
