Issue with facetted plots

[pcroteau]

First, let me thank you for this awesome package. I use it quite a lot since I found out about it.

I seem however to have stumbled upon a bug that occurs when one wants to label only some points of a given facet of a facetted graph.

Here's some fake data to illustrate the problem:

set.seed(1234)
dtf <- data.frame(y=rnorm(4), x=rnorm(4), g=gl(2,2), lb = letters[1:4], stringsAsFactors = F)

dtf2 <- dtf
dtf2$lb[3] <- ""

dtf3 <- dtf2
dtf3$lb[4] <- ""

Now, the following works well for both geom_text and geom_text_repel:

library(ggrepel)
ggplot(dtf, aes(x,y,label=lb)) + facet_wrap(~g) + geom_point() + geom_text()
ggplot(dtf, aes(x,y,label=lb)) + facet_wrap(~g) + geom_point() + geom_text_repel()

It works well with both dtf and dtf2. Below I report the geom_text_repel version with dtf.

However, for dtf3, geom_text work well while I get the following error with geom_text_repel:

Error in repel_boxes(data_points = cbind(x$data$x, x$data$y), point_padding_x = point_padding_x,  : 
  not compatible with requested type

Thanks for reporting this bug with the code snippet and the figure!

I'd be happy to review a pull request that fixes this bug. Otherwise, I'll have to come back to this issue when time allows.

@pcroteau The issue should be fixed in 0.6.9

Try re-installing the latest version and please re-open this issue if you run into any problems.

devtools::install_github("slowkow/ggrepel")

Thanks again for reporting this bug!
