plotParallel {nFactors} | R Documentation |
Plot a scree plot adding information about a parallel analysis.
plotParallel(x, eig = NA, legend = TRUE, ylab = "Eigenvalue", xlab = "Component", main = "Parallel Analysis" )
x |
Result of a previous parallel analysis |
eig |
Eigenvalues |
main |
Title of the plot |
xlab |
Label of the x axis |
ylab |
Label of the y axis |
legend |
Logical indicator of the presence or not of a legend |
If eig
is FALSE
the plot shows only the parallel analysis without eigenvalues.
Nothing returned.
