Dear all, With normal plotting, one can size a set of points in a plot using a vector argument to cex in the points() function. This works whether you are using one of the standard R symbols (i.e. 19+) or some ascii symbol, such as '/'
eg: plot(1:10, 1:10, type='n'); points(1:10, 1:10, cex = 1:10, pch = '/') Trying to make the transition to ggplot2, I find that the aesthetic size mapping does not apply if i do geom_point(..., shape='/') -- the points show up looking like '/' but they are not sized. Is there anything to do about this? eg: ggplot(data = data.frame(x = 1:10, y = 1:10, size = 1:10), aes(x = x, y = y)) + geom_point(mapping = aes(size = size), shape = '/') the plot that I'm making really needs a vertically oriented mark, not a round-ish point/square/triangle that takes up a lot of area. am I totally out of luck? thanks, mike -- View this message in context: http://www.nabble.com/sizing-non-vector-point-shapes-in-ggplot2-tp17863871p17863871.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
