Dear gretl users, I have created a matrix with 4 columns and 1000 rows and now I'd like to use the boxplot command on it, but it is (despite it should) not working... what am I getting wrong? Here is a MWE: ---------- nulldata 1000 matrix A=zeros(1000,4) loop for r=1..1000 loop for c=1..4 A[r,c]= randgen1(u,0,c) endloop endloop boxplot --matrix=A --output=display ------------ Error msg: ? boxplot --matrix=A --output=display Command has insufficient arguments

The quick-help documentation needs an update than, I guess: "Generally, the argument varlist is required, and refers to one or more series in the current dataset (given either by name or ID number). But if a named matrix is supplied via the --matrix option this argument becomes optional: by default a plot is drawn for each column of the specified matrix." To me this implies that I do not need to specify the columns. This option is not even mentioned.
