Linear regression plot with residual plot

Description

Plot data, the linear model, and a residual plot simultaneously.

Usage

lmPlot(
  x,
  y,
  xAxis = 0,
  yAxis = 4,
  resAxis = 3,
  resSymm = TRUE,
  wBox = TRUE,
  wLine = TRUE,
  lCol = "#00000088",
  lty = 1,
  lwd = 1,
  xlab = "",
  ylab = "",
  marRes = NULL,
  col = "#22558888",
  pch = 20,
  cex = 1.5,
  xR = 0.02,
  yR = 0.1,
  xlim = NULL,
  ylim = NULL,
  subset = NULL,
  parCustom = FALSE,
  myHeight = c(1, 0.45),
  plots = c("both", "mainOnly", "resOnly"),
  highlight = NULL,
  hlCol = NULL,
  hlCex = 1.5,
  hlPch = 20,
  na.rm = TRUE,
  ...
)

Arguments

x	The x coordinates of points in the plot.
y	The y coordinates of points in the plot.
xAxis	The maximum number of x axis labels.
yAxis	The maximum number of y axis labels.
resAxis	The maximum number of y axis labels in the residual plot.
resSymm	Boolean determining whether the range of the residual plot should be symmetric about zero.
wBox	Boolean determining whether a box should be added around each plot.
wLine	Boolean determining whether to add a regression line to the plot.
lCol	The color of the regression line to be added.
lty	The line type of the regression line to be added.
lwd	The line width of the regression line to be added.
xlab	A label for the x axis.
ylab	A label for the y axis
marRes	Margin specified for the residuals.
col	Color of points.
pch	Plotting character.
cex	Plotting character size.
xR	Scaling the limits of the x axis. Ignored if xlim specified.
yR	Scaling the limits of the y axis. Ignored if ylim specified.
xlim	Limits for the x axis.
ylim	Limits for the y axis.
subset	A subset of the data to be used for the linear model.
parCustom	If TRUE, then the plotting margins are not modified automatically. This value should also be TRUE if the plots are being placed within a plot of multiple panels.
myHeight	A numerical vector of length 2 representing the ratio of the primary plot to the residual plot, in height.
plots	Not currently utilized.
highlight	Numerical vector specifying particular points to highlight.
hlCol	Color of highlighted points.
hlCex	Size of highlighted points.
hlPch	Plotting characters of highlighted points.
na.rm	Remove cases with NA values.
...	Additional arguments to plot.
