multiHist: ## Plot one or more histograms on the same axes using lines

In lwaldron/LeviRmisc: Levi's miscellaneous handy R functions

Description

If obj is a vector, this function acts like graphics::hist, but only sketches a line along the top of the histogram, rather than plotting bars. If obj is a matrix or dataframe, it creates a line for each column.

Usage

multiHist(obj, lty = 1:ncol(obj), lwd = rep(1, ncol(obj)), col = rep(1, 
    ncol(obj)), ...)

Arguments

obj	A numeric/integer vector, dataframe, or matrix. If obj is a dataframe or matrix, a histogram line will be created for each column.
lty	lty for each histogram line.
lwd	lwd for each histogram line.
col	col for each histogram line.
...	Extra arguments passedon to graphics::hist

Value

Invisibly returns the output of hist() obj (vector) or the first column of obj (matrix or dataframe).

multiHist(x[, 1])
multiHist(round(x[, 1] * 1000), xlab="x*1000", main="Integer input")
