uScree
Plot a usual scree test of the eigenvalues of a correlation matrix.
plotuScree(Eigenvalue, x = Eigenvalue, model = "components", ylab = "Eigenvalues", xlab = "Components", main = "Scree Plot", ... )
Eigenvalue |
depreciated parameter: eigenvalues to analyse (not used if x is used, recommended) |
x |
numeric: a vector of eigenvalues, a matrix of
correlations or of covariances or a data.frame of data |
model |
character: "components" or "factors" |
main |
character: title of the plot (default is Scree Plot ) |
xlab |
character: label of the x axis (default is Component ) |
ylab |
character: label of the y axis (default is Eigenvalue ) |
... |
variable: additionnal parameters to give to the eigenComputes function |
Nothing returned by this function.
