How to vectorize plot graphic?
Thanks Jeff. I'm not sure to which manual you are referring. Nothing like what you mention is found here: http://cran.r-project.org/manuals.html . Perhaps you're referring to The Data Import/Export Manual, but that wouldn't make sense. Googling "R Input/Output manual" doesn't help. Regarding the device, I'm in R-Studio, plotting to the standard device there (I suppose). In any case, I'm not totally sure what the interface between R-Studio's plot window and the R instance is. I think that, as you say, what I'm getting is as expected. I zoom and the plot zooms as expected. So, I guess that part is solved. However, the writing to .wmf as a bitmap instead of a vector is still a mystery to me. Thanks, Allie

You have mentioned nothing about the device you are writing the plot to. If to the default and you are copying it from there as a bitmap, then what you are describing sounds as expected. Read the R Input/Output manual (again) for other output options.

Hi Folks, Using ggplot, I've produced the following graphic: http://i.imgur.com/39a139C.png The graphics in the plot seem to be bitmapped and not vectorized. That is, the vertical and horizontal lines jump rows of pixels instead of having just nice, angled lines. Any thoughts about how to get these graphics vectorized? Or am I misunderstanding something? Another example: The code: require(ggplot2) df = data.frame(x = c(1:360), y = sin(seq(0,2*pi*3,length.out = 360))) ggplot(df, aes(x=x, y=y)) + geom_line() produces http://i.imgur.com/mjjSKih.png Perhaps what I'm dealing with here is my screen resolution. However, I use ggsave() to save .wmf files, and those also turn out to be bitmaps and not vectors. Thanks, Allie [[alternative HTML version deleted]]
