ggplot2 release coming soon
Hadley Wickham
We're getting very close to another release of ggplot2. I think it's
now at the point where it would be useful for more people to start
trying out the development version. The easiest way to get it is:
install.packages("devtools")
library(devtools)
dev_mode() # to avoid clobbering existing install
install_github("scales")
install_github("ggplot2")
Please read the news file for an extensive list of changes:
news(Version == "0.9.0", package = "ggplot2")
If you do discover problems, please sign up for the ggplot-dev mailing
list and discuss them there. That will help keep discussions about
the released version separate from the development version.
You can follow progress on bugs etc at
https://github.com/hadley/ggplot2/issues?milestone=1
Thanks!

ggplot2 0.9 now passes R CMD check, so unless I discover any show
stopper bugs I'll be releasing it to CRAN in the next couple of days.
Again, it would be greatly appreciated if you tried it out with a few
of your plots - I'm trying to get better at writing automated tests,
but there's still a long way to go.
install.packages("devtools")
library(devtools)
dev_mode() # to avoid clobbering existing install
install_github("scales")
install_github("ggplot2")
You can see all the changes (and there are a lot!) by running:
news(Version == "0.9.0", package = "ggplot2")

A minor thing, I can't get the news line to work for some reason,
news(Version == "0.9.0", package = "ggplot2")
Error in charToDate(x) :
character string is not in a standard unambiguous format
Also, have you considered keeping a ggplotGrob function? (recent post
in ggplot2-dev)

moved to the scales package I gather.
When I run this:
df <- data.frame(
x = sample(10, 20, replace = TRUE),
y = sample(10, 20, replace = TRUE),
grp = rep(letters[1:2],length.out = 20)
)
ggplot(df, aes(xmin = x, xmax = x + 1, ymin = y, ymax = y + 2)) +
geom_rect(aes(fill = grp)) +
scale_fill_manual(values=alpha(c('red','blue'),0.5))
I get the following error:
Error in scale$palette(n) : could not find function "alpha"
If I change that to
scale_fill_manual(values=scales:::alpha(c('red','blue'),0.5))
it runs and produces the plot, but with the "full" colors rather than
the alpha-ed versions of the color. Running both
scales:::alpha("red",0.1)
scales:::alpha("red",1)
at the console seem to produce the correct output, though. My session

transparency digits when supplying hex colors. I've tried
scale_fill_manual and scale_colour_manual so far. For instance:
dat <- data.frame(x = 1:10,y = 1:10,grp = rep(letters[1:2],length.out
= 10))
ggplot(dat,aes(x = x,y = y)) +
geom_point(aes(colour = grp)) +
scale_colour_manual(values = c('#FF00001A','#0000FF1A'))
is the same as if you omitted the trailing 1A.

Out of curiosity, is there a specific reason not to use alpha as a
setting in the layer instead?
ggplot(df, aes(xmin = x, xmax = x + 1, ymin = y, ymax = y + 2)) +
geom_rect(aes(fill = grp), alpha=0.5) +
scale_fill_manual(values=c('red','blue'))
b.

think this is a minor issue.
I just happened to have some code with the colors passed in directly
(or using alpha()) and thought I'd mention it. But if the solution is
simply to set alpha in the geom, that's fine with me.

gridExtra should work fine, but you probably won't be able to use
ggExtra (and I've removed it from r-forge). Which functions
specifically have you been using?

FYI you should never use ::: and rarely use ::. Just load scales
explicitly with library(scales)
For the other issue, I've created a bug report at

plots. Hadley's comment below seems to tell one how to install the
new ggplot but I am not sure how to revert back to the old one. If
there is a link (it does not have to be specific to ggplot) on how to
revert from dev_mode(), it would be much appreciated. I tried
?dev_mode().

I don't get the same error message you reported in 0.9.0:
> g <- tableGrob(head(iris[1:3,]))
> d <- qplot(1,1, geom="blank")
> d + annotate("custom", x=1, y=1, grob=g)
Error: No geom called custom
See ?annotate in 0.9.0. The first argument of annotate() is geom, so
it's expecting the quoted name of an existing geom. Since there is no
geom_custom(), an error is thrown. What were you trying to annotate?
It's entirely possible that there is another way to do it.
Since this problem arose in 0.8.9, it wasn't caused by the changes in
the development version, although it clearly persists there.

changing the direction of an existing one.

the simple example worked on my end in 0.9.0 - a nice table in the
middle of the plot area. As for the additional example you provided,
I'd suggest using tableGrob() in gridExtra to create the grob first
and use a simpler call in annotate(). The error I get in 0.9.0 is:
> library('plyr')
> library('reshape2')
> dsmall <- diamonds[sample(nrow(diamonds), 100), ]
> dsmall <- rename(dsmall, c("cut" = "Cut"))
> ggplot(dsmall, aes(carat, price)) +
+ geom_point() +
+ annotate("custom", x=0, y=11000, table=ddply(dsmall,"Cut", summarise,
+ Avg_price = mean(price)),
+ gp=gpar(cex=1), just=c("left","bottom"), show.rownames=F,
+ gpar.coretext = gpar(fontsize=9,
+ col="lightblue",fontface="bold.italic")) +
+ geom_text(aes(x=0.4, y=16000, label="Table of Means"),
colour="red")
Error in grobWidth(grob) : argument "grob" is missing, with no default
Maybe you could get away with something like
annotate(..., grob = tableGrob(ddply(dsmall, "Cut", ...)
but Baptiste is the expert on matters involving gridExtra. All I'm
suggesting is to break up the code a bit so that it's easier to see
where things might go wrong.

a data.frame as input). I attach a script that tries to conform better
with the prototype of annotation_raster in ggplot2. Would that be
useful enough to belong in ggplot2 after some polishing?

Sorry but I've lost track of what we're talking about: an example of
using annotation_custom, the code itself, an example intended for
gridExtra, or ggplot2? I'm assuming the first two; I'll try to submit
a pull request with the file I attached earlier as soon as I
understand what that involves.
