...bug in scatterplot matrix where all scatterplots were transposed! * qplot: should now work better within functions * quickplot added as an alias of qplot, to avoid confusion with qunif, etc * scale_*: better error message if you add a scale without a matching aesthetic mapping in the plot * scale_identity no longer converts everything to character * scale_identity: grob argument renamed to guide * stat_*: made all statistics more robust to errors * stat_quantile: fixed bug when only drawing a single quantile * stat_smooth: returns silently if <2 non-missing data points Minor aesthetic i...

Dear useRs, I'm trying to specify the colour of a factor with ggplot2. The example below gets me close to what I want, but it's missing a legend. Any ideas? Thanks, Thierry library(ggplot2) dataset <- data.frame(x = rnorm(40), y = runif(40), z = gl(4, 10, labels = LETTERS[1:4])) ggplot(data = dataset, aes(x = x, y = y, group = z)) + geom_point(colour = c("red",
