)
loadings

)

autoplot(object, type = c("screeplot", "scores", "loadings"), k = NULL, ...)
Arguments
- object
an object of class gt_pca
- type
the type of plot (one of "screeplot", "scores" and "loadings")
- k
the principal components to be plotted: for scores, a pair of values
e.g. c(1,2); for loadings
