Commonly used graphical parameters are:
pch
A vector of plotting characters or symbols. This can either be a single character or an integer code for one of a set of graphics symbols.
cex
A numerical vector giving the amount by which plotting characters and symbols should be scaled relative to the default.
col
The colors for lines and points. Multiple colors can be specified so that each point can be given its own color.
bg
The background color for the open plot symbols given by
pch = 21:25
.
viz_*()
is called for its side-effects: it results in a graphic
being displayed. Invisibly returns x
.
Be careful: graphical parameters are silently recycled.

## Load data
data("iris")
## Compute principal components analysis
X <- pca(iris, scale = TRUE)
## Plot individuals
viz_individuals(X, panel.last = graphics::grid())
## Plot variables
viz_variables(X, panel.last = graphics::grid())
## Graphical parameters
## Continuous values
viz_individuals(X, highlight = iris$Petal.Length, pch = 16)
viz_individuals(X, highlight = iris$Petal.Length, pch = 16,
col = grDevices::hcl.colors(12, "RdPu"))

cex = c(1, 2))
viz_variables(X, highlight = "contribution",
col = grDevices::hcl.colors(12, "BluGrn", rev = TRUE),

## Discrete values
viz_individuals(X, highlight = iris$Species, pch = 21:23)
viz_individuals(X, highlight = iris$Species, pch = 21:23,
bg = c("#004488", "#DDAA33", "#BB5566"),
