Re: R dependencies

[Vicente Vera <vicentemvp@gmail.com>]

Hi,

Sure. The error message is this:

X11 font -adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*, face 5 at size
15 could not be loaded

No plot is being drawn; only a blank window appears.

The code:

ggplot(data = fig1, aes(x = Var1, y = Freq, fill =
brewer.pal(length(levels(the_data$VARIABLE1)), "Set3"))) +
    geom_bar(stat = "identity") +
    scale_fill_identity() +
    labs(x = "x", y = "y") +
    geom_text(aes(label = perc), vjust = 2, size = 4, colour =
"black", fontface = "bold") +
    scale_x_discrete(labels = c("a", "b", "c")) +
    theme(panel.background = element_blank(),
          line = element_blank(),
          axis.text.y = element_blank())

On my base system, R 3.2.1 + ggplot2 draws the plot with no problem.

It might be related to a missing font or font alias in the Guix store
(not familiar enough with it to catch the issue).

Now, I didn't installed ggplot2 through Guix, so that could be a problem.
