Hello,
I have got a data frame looking like this:
Country Sector m-value
USA Banks 38.5
USA Media 17
USA hospitals 2.3
Germany Banks 56
Germany real estate 1
Italy Banks 34
Italy Media 23
Italy real estate 78
Italy Beverage 23
....
I would like to have a graph, let's say country on the x-axis, sector
at the y-axis, and for
each compination of country and sector a square in blue. The shade of
the color should depend on the
level of the m-value.(This graph should look more or less like the
graph when you use corrgram() to display correlation)
I tried ggplot() but I didn't get far. So it would be really nice if
somebody could help me.
Best regards
Claudia
