xyhist: A scatterplot with marginal histograms

Description

The function produces a scatterplot between the 'y'-axis variable and the 'x'-axis variable, but also adding the marginal histograms for both variables.

Usage

xyhist(
  x = x,
  y = y,
  col.x = "blue",
  col.y = "red",
  xlab = NULL,
  ylab = NULL,
  x.lim = NULL,
  y.lim = NULL
)

Value

The function returns the above described graph.

Arguments

x

A numeric vector representing the X-axis variable

y

A numeric vector representing the Y-axis variable

col.x

(optional) A string specifying the color of the histogram of the X-variable. Default is "blue".

col.y

(optional) A string specifying the color of the histogram of the Y-variable. Default is "red".

xlab

(optional) A string specifying X-axis label. Default is "xvar".

ylab

(optional) A string specifying Y-axis label. Default is "yvar".

x.lim

(optional) A vector of two elements with the limits of the Y-axis. Default is the range of the X-variable.

y.lim

(optional) A vector of two elements with the limits of the Y-axis. Default is the range of the Y-variable.
