The results are displayed in the active display frame on the user's graphics monitor. d.correlate erases the active frame before displaying results.
The layern parameters supply the names of two to four existing raster map layers to be included in the correlation.
If three or four map layers are specified, the correlation among each combination of two data layers is displayed.
