PCA problem in R
Dear all: When I have more variables than units, say a 195*10896 matrix which has 10896 variables and 195 samples. prcomp will give only 195 principal components. I checked in the help, but there is no explanation that why this happen. Can we get more than 195 PCs for this case? Thank you very much. Best! Alan Aug-12-2005
