freqpoly: Frequency polygon plot

In USCbiostats/ENmixUSC: Data preprocessing and quality control for Illumina HumanMethylation450 and MethylationEPIC BeadChip (USC version)

Description

Similar to histogram, frequency polygon plot can be used to display data distribution.

Usage

freqpoly(mat, nbreaks=15, col="black", xlab="", ylab="Frequency", 
         type="l",append=FALSE,...)

Arguments

mat	A numeric vector
nbreaks	Number of bins for frequency counting
col	color code
xlab	x-axis lable
ylab	y-axis lable
type	character indicating the type of plotting; actually any of the 'type's as in 'plot.default'.
append	TRUE or FALSE, whether to create a new figure or append to the current figure.
...	Further arguments that get passed to the function "plot"

Value
