In xuz1/ENmix: Data preprocessing and quality control for Illumina HumanMethylation450 and MethylationEPIC BeadChip

Frequency polygon plot

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

Frequency polygon plot.
