With data frames, each variable is a column, but in the original matrix, the rows represent the baskets for a single player. So, in order to get the desired result, you first have to transpose the matrix with t() before converting the matrix to a data frame with as.data.frame(). Looking at the structure of a data frame. If you take a look at the object, it looks exactly the same as the.
