How do a plot several columns of a matrix at once in a single plot versus a single x-variable?
The default plot.matrix or plot.dataframe commands plot each column versus each other column in several sub-plots. I want to plot each column versus a single other vector (x) as several lines or points in one plot. I can do it by hand: get the range of all variables (i.e. columns of the matrix or dataframe), initiate an empty plot command, loop through all the columns and issue a lines or points command. I guess there is a predefined sophisticated function for that, however, I was not able to find it. Does someone know where I find such a function?
