Hello,
I am a new user of R statistical project. So, I have a matrix (4 columns and
330 rows) and I would like to have PCA (Principal Component Analysis). Besides,
I would like to draw every 30 rows from 330 with a different colour but I dont
know how.
Could you help me by showing how can I draw every 30 rows with a different
colour?
Thank you very much
Selim
