With >as.matrix(MEAN[unlist(lapply(MEAN, is.numeric))]) I will get two colums not three and only the last colum are my values (MEAN[,3]). The first is only a rising number.
I also tried: >MEASURE <- sapply( MEAN, as.numeric ) resp. >MEAN <- unlist(MEAN) >MEASURE <- matrix(MEAN, ncol=3, byrow=FALSE) But then, the first colum is +1 greater and the second colum is +1)*10 greater.
