data

a data matrix. Should contain numerical (continuous) data.

columns

alpha

an option to set the transparency in scatterplots for large data. Defaults to 1.

corMethod

method argument supplied to cor

# NOT RUN {
data(flea)
ggscatmat(flea, columns = 2:4)
ggscatmat(flea, columns = 2:4, color = "species")
