ScatterPlot: ScatterPlot

In FranceschiniS/LMWiRe: R Routines for Linear Model with Wide Response

Description

Draws scatter plots.

Usage

ScatterPlot(x, y, points_labs = NULL, createWindow = FALSE,
  main = NULL, color = NULL, pch = NULL, size = 1, cex.lab = 3,
  xlab = NULL, ylab = NULL, legend_pch = NULL, legend_color = NULL,
  drawEllipses = FALSE, typeEl = "norm", levelEl = 0.9)

Arguments

x	x-axis values.
y	y-axis values.
points_labs	If not NULL, will show the labels for each observation on the plot.
createWindow	If TRUE, will create a new window for the plot.
main	Plot title. If NULL, default title is provided.
color	Optional character, factor or numeric vector giving the color of the observations. If length(color) = 1, the unique color is kept for all the points.
pch	Optional character, factor or numeric vector giving the pch of the observations.
size	The points size.
cex.lab	The size of points labels.
xlab	If not NULL, label for the x-axis.
ylab	If not NULL, label for the y-axis.
legend_pch	If not NULL, the labels for the pch legend.
legend_color	If not NULL, the labels for the color legend.
drawEllipses	If TRUE, will draw ellipses with the ggplot2::stat_ellipse with groups coresponding to the color vector.
typeEl	The type of ellipse, either "norm" (multivariate normal distribution), "t" (multivariate t-distribution) and "euclid" draws a circle with the radius equal to level, representing the euclidean distance from the center.
levelEl	The confidence level at which to draw an ellipse.

Details

If type.obj is 'OPLSDA', axes = 1 represents the predictive score vector, axes = 2 represents the first orthogonal score vector, etc.

Value

A score or loading plot in the current device.

Examples

x <- c(1:20)
y <- sample(20)
colors <- c(rep(1,10), rep(2,10))
points_pch <-  c(rep(17,10), rep(18,10))
labels <- as.character(c(1:20))
# automatic legend names and values assignment
ScatterPlot(x = x, y = y, points_labs = labels, createWindow=FALSE,
           main = 'Scatter plot', color = colors, pch = points_pch,
           xlab = "x axis", ylab = "y axis")

# decide on the color or pch values
legend_color = c(rep("A", 10), rep("B", 10))
legend_pch = c(rep("C", 10), rep("D", 10))
ScatterPlot(x = x, y = y, points_labs=labels, createWindow=FALSE,
           main = 'Scatter plot', color = colors, pch = points_pch,
           xlab = "x axis", ylab = "y axis",
           legend_pch = legend_pch,legend_color=legend_color)
