Hi,
I was trying to replicate one of the graphs given on the ggplot2 website. I
have given a sample code below. I would like to combine the legends, since
each color is uniquely mapped to a shape.
###
library(ggplot2)
leaves <- letters[1:8]
mat <- matrix(sample(1:1000,32),nrow=16,ncol=2)
colnames(mat) <- paste('t',1:2,sep='')
df <- as.data.frame(cbind(mat,leaves))
vals <- 1:length(leaves)
names(vals) <- leaves
p <- ggplot(df,aes(t1,t2))
p + aes(shape = factor(leaves)) + geom_point(aes(colour =
factor(leaves))) + scale_shape_manual("",values=vals)
####
Which parameter do I need to change?
thanks!
