Warning: Font family not found in Windows font database

[Andrie de Vries]

I am updating one of my packages to work with ggplot2 version 0.9.2. This generates a set of warnings that I haven't seen before.

To do this, I installed the github version using devtools:

library(devtools)
dev_mode(TRUE)
install_github("gtable")
install_github("scales")
install_github("ggplot2")
library(ggplot2)
ggplot(iris, aes(Sepal.Width, Sepal.Length)) + geom_point()

This creates the plot, but also 8 identical warnings:

Warning messages:
1: In grid.Call(L_textBounds, as.graphicsAnnot(x$label), x$x, x$y,  :
  Font family not found in Windows font database

Do you have any ideas or suggestions on how to fix this?

Hi Andrie -
Thank you for reporting this! It looks like this is related to a
change in the default font in the 0.9.2 release candidate -
previously, the default font was unspecified, but in the RC, it was
set to Helvetica, which isn't present on all Windows machines. I've
changed it back to the previous default value, which was just "".

To install the updated RC version, use the following:
library(devtools)
dev_mode()
install_github("gtable", branch = "gtable-0.1.1-rc")
install_github("scales", branch = "scales-0.2.2-rc")
install_github("ggplot2", branch = "ggplot2-0.9.2-rc")

I haven't added the change to the master branch yet, so if you don't
specify the branch, you won't get the fixed version.
