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 only thing I could find about this was a rather old post by Sven: http://lists.wfu.edu/pipermail/gretl-devel/2009-April/001894.html

Any help is appreciated

Frederik
