plotParallel | R Documentation |
Plot a scree plot adding information about a parallel analysis.
plotParallel(parallel, eig = NA, x = eig, model = "components", legend = TRUE, ylab = "Eigenvalues", xlab = "Components", main = "Parallel Analysis", ...)
parallel |
numeric: vector of the results of a previous parallel analysis |
eig |
depreciated parameter: eigenvalues to analyse (not used if x is used, recommended) |
x |
numeric: a |
model |
character: |
legend |
logical: indicator of the presence or not of a legend |
ylab |
character: label of the y axis |
xlab |
character: label of the x axis |
main |
character: title of the plot |
... |
variable: additionnal parameters to give to the |
If eig
is FALSE
the plot shows only the parallel analysis
without eigenvalues.
Nothing returned.
