After obtaining data of cancer patients from 4 different time intervals using raman spectroscopy ,how to concatenatethe data from all these 4 groups for PCA analysis? Can anyone share the code?
If I am concatenating the way they mentioned, I am getting double the number of rows as compared to the initial one, rather it should be added as columns, but since there are 4 groups, taking transpose may not be effective as well. Is there any other way @mohammed deeb
