Additionally I can get the output as a matrix in form atomic [1:613] 3.01 4.1 3.04 3.81 3.55 3.37 3.09 4.1 3.61 6.36 ... - attr(*, "acs")= num 47.6 where "acs" is the average size. Each height value in the vector has a corresponding number relating to the location in the dataset. When I change the vector to matrix this looks like the row name but it isn't as rownames(clusters) yields NULL. Do you have any idea how to abstract these values?
