Can't print full pca

[nspyrison]

I can't return the last dim of the pca, p-1 seems to work.

  m <- as.matrix(mtcars)
  Rdimtools::do.pca(m, ndim = ncol(m))
#> Error in dt_pca(X, myndim, myprep, mycor): * do.pca : 'ndim' should be in [1,ncol(X)).

Hi @nspyrison. When you apply PCA with full dimension as of your ncol(m), this is simply whitening. In the spirit of reducing dimensionality of the data, I made a common imperative to accept that ndim should be smaller than the number of variables.
