/CRPLOT <data>,<C1>,<C2>,<C_coord>,<S_coord> / K.Vehkalahti
creates a correspondence plot of dimensions <C1> and <C2> so that the
information from <data> and two matrices are presented in the same
coordinate system. These plots are typical in correspondence analysis. The
data are actually a table of frequencies. See CORRESP? for more information
on correspondence analysis. /CRPLOT assumes that the <data> is a Survo data
file (.SVO).
CORRESP saves the row coordinates of the table to variables <C1> and <C2>,
and the column coordinates to a matrix file <C_coord>. By default the name
of this matrix file is CR_COORD.M .
The column coordinates of supplementary variables (if any) can be given by
the matrix <S_coord> (by default CR_SUPPC.M). If no variables are activated
by `S' in <data>, <S_coord> is not used.
Specification POINT can be used to give the label variable for the row
coordinates. By default, if the first active variable is a string, it will
serve as a label variable.
The sucro gives the user a ready made work scheme, where various parameters
can be modified, and the picture then easily re-produced. A PostScript
version of the picture can be created from that scheme by one sucro command
as well.
