Hi everyone,
I combined three categorical arrays and obtained a 1000×3 matrix (associated with 1000 images I am working on). Basically, one of the three variables holds the path to the images, giving something along the lines of:
Users\MyUserName\Desktop\MyProject\MyImages\dogs1\dogs1.1.pngUsers\MyUserName\Desktop\MyProject\MyImages\dogs1\dogs1.2.png Users\MyUserName\Desktop\MyProject\MyImages\dogs2\dogs2.1.png
and so on.
My goal is to group the rows of the matrix according to the last subfolder (i.e. dogs1 and dogs2 in my simplified example) they are associated with under the "path" variable. I would like to do so in order to automatically perform basic stats on each group (mode, specifically).
Is this even feasible with such an "unconventional" variable? If not, is there a way to (automatically) replace the "path" array with another (normal) categorical array such as "dog1", "dog2" etc. ? This would also solve the issue.
I tried to look at different questions but couldn't find any that dealt with this issue, so I would really appreciate any help.
Thank you very much.
Best regards
