choices	Either a logical/integer vector to indicate which PCs to be returned, or NULL or missing, in which case all PCs are returned
compact	Logical, either a compact label is returned, see examples.

A character string vector of the same length as choices (or the same length as the column count of the PCAScoreMatrix), which are the labels of the PCs

Examples

pcaMat <- PCAScoreMatrix(matrix(rnorm(15),ncol=3), c(0.25, 0.15, 0.1))
expVarLabel(pcaMat)
