Dear all,
The following example code produces a graph with ggplot2, to which I
add several vertical lines of arbitrary colors. I am not satisfied
with the legend: it automatically adds some vertical lines which I'd
rather not see (they confuse the reader rather than add information
in this case).
library(ggplot2)
dfr <- data.frame(values = sin(1:50/10),
fact = rep(c("short", "long"), each=25, length=50),
fact2 = rep(1:10, length=50))
p <- qplot(fact2, values, data=dfr, colour=fact)
p + geom_vline(intercept=c(5), colour = 1) +
scale_shape_manual(name="fact", values=1) # tried this, but useless
here
Any tips on changing these settings would be welcome!
Sincerely,
baptiste
