Thanks Ákos,
I did as you mentioned:
> is.factor(libro1$Treat)
[1] FALSE
> libro1$Treat <- as.factor(libro1$Treat)
> palette <- setNames(object = c(“red”, “green3”, “black”, “blue”), nm = levels
> (Libro1$Treat))
> chart.Correlation(libro1[,1:4], histogram = T, pch = 19, bg =
> palette[Libro1$Treat])
But nothing happens. I got again the correlation plot but doc values are not in
colour following the Treat classification
Thanks for your time.
Best
Manuel

Asunto: Re: [R-sig-eco] correlation plot in color
Dear Manuel,
are you sure that Libro1$Treat is really a categorical column (instead of
character)?
The example code that you sent us works for categorical data:
is.factor(get(data(iris))$Species)
TRUE
If is.factor(Libro1$Treat) is FALSE, then you should convert it from character
to factor, before creating the color palette and calling
chart.Correlation():
Libro1$Treat <- as.factor(Libro1$Treat)
Have a nice week,
Ákos
