All data frames "look like" matrices, but none of them "are" matrices. I think we need you to follow the Posting Guide and supply an R reproducible example that gives us a concrete idea what the data structure is that you are working with, and an example of what you expect to get out of the code you want us to show you. The dput function can be a lifesaver in helping you provide R code that can reproduce in our R sessions the data you have in front of you. Read more in [1][2] and [3].
