It is important that it is without header in order to convert it to a matrix. data3=data.matrix(data3) # convert table to a data matrix. Important step because otherwise data will be treated as a dataframe and not as a datamatrix. x=c(1:10) # define x variable. In this case 10 values. y=c(1:8) # define y variable. In this case 8 values
