Updated reshape and ggplot
Hi everyone,
This is a short announcement for the users of ggplot and reshape. I
have just released new versions of each that fix bugs when used with R
2.5.0:
* reshape was having problems with missing combinations of variables
* errorbars in ggplot weren't working.
I've you've been having problems with either of these, please upgrade.

ggplot facet label font size
How do I change the font size in the facet labels along the edges of the
plot?
For example (from the ggplot help file):
p<-ggplot(tips, sex ~ smoker, aesthetics=list(x=tip/total_bill))
gghistogram(p)
In this plot, the facet labels are "smoker: No", "smoker: Yes", "sex:
Female", "sex: Male". What command can I use to reduce the font size of

ggplot 2 - editing in the "panel_1_1" viewport
Hi All,
I am trying to find out how to access the components of a ggplot plot, and I
found this reply from Paul Murrel
http://www.nabble.com/navigating-ggplot-viewports-tt14826352.html#a15056223.
I tried it, and it works.
However, I am trying to develop some functions that will do the drawing
"automatically", and usually I will not know the full name of the grob that
has the layout vp,

ggplot: Trouble with xlim() and discrete scales
I'm learning ggplot and am a little confused. Sometimes discrete scales work
like I'd expect, and sometimes they don't. For example...
This works exactly like one would expect:
df<-data.frame(names=c("Bob","Mary","Joe","Bob","Bob"))
ggplot(df,aes(names))+geom_histogram()
But this yields an error:

[ggplot] trouble with ggabline and log-log-plots
Hello,
I'm trying to generate a log-log plot with ggplot. Within this plot, I
would like to draw a straight line with the help of ggabline which does
not work. The code is
pl1 <- qplot(correlFunc, correlFunc.ref, data=all, log=c("xy"))
pl1 <- ggabline(pl1, slope=1, intercept=0)
print(pl1) ## no line in plot :(
I can produce plots as I want, if I transform all values before

Broke ggplot...
It appears I broke ggplot in my script, but that maybe it is because the caffeine has worn off or maybe it is late in the day. I thought I was beginning to understand ggplot, but I have encountered a silly little issue.
For some reason the following does not produce a histogram with fill due to the Person's characteristics:

ggplot not showing all the years on the x-axis
Dear R helpers,
I am currently having hard time fixing the values on the x-axis of a plot
with ggplot: even though I have 12 years, ggplot plots only 3 of them.
Here is my example:
library(ggplot2)
ii <- 2000:2011
ss <- rnorm(12,0,1)
pm <- data.frame(ii,ss)
tmpplot <- ggplot(pm, aes(x = ii, y = ss))
plot <- tmpplot + geom_line()
plot
In my case, ggplot reports on the year 2000,

ggplot adjust two y-axis
Hi,
I don't know the axis mecanism well enough in ggplot but using the original
barplot function you can add an axis on the right using the axis function.
Here is an example:
test <- as.table(matrix(c(2,10,3,11), 2,2))
barplot(test, beside = TRUE, col = scales::brewer_pal(palette = 1)(2))
axis(4, at = c(0, 5, 10), labels = c(0,50,100))

ggplot in a function confusion!
Whats going on here?
df<-data.frame(x=1:10,y=1:10)
ggplot()+geom_point(data=df,aes(x=x,y=y)) ## this is the normal usage
right?
ggplot()+geom_point(data=df,aes(x=df[,1],y=df[,2])) ## but I can also feed
it column indices
ggplot()+geom_point(aes(x=df[,'x'],y=df[,'y'])) ## or column names.
## but if i wrap it in a function...

ggplot adjust two y-axis
Dear Charles-Edouard
Thanks a lot. Yes indeed barplot sounds excellent.
Unfortunately, the scale of the smaller axis is fixed, even If I am able to
draw to axes. The idea is to expand the scale to the scale to the second
axis for comparison.
F1 <- as.table(matrix(c(50,11,6,17,16,3,1,2237,611,403,240,280,0,0), 2,7))
barplot(F1, beside = TRUE, col = c("blue", "grey"))

ggplot2: changing axis labels in ggplot()
Hi all,
For various reasons, I need to use ggplot instead of qplot for a complex
figure. Everything is working fine, except I cannot figure out how to rename
the axis labels in ggplot. I have pasted a simple example below. Any ideas
on what I am doing wrong?
Thanks for your help.

Ggplot barchart drops factor levels: how to show them with zero counts?
Hello,
When plotting a barchart with ggplot it drops the levels of the factor for
which no counts are available.
For example:
library(ggplot)
mtcars$cyl<-factor(mtcars$cyl)
ggplot(mtcars[!mtcars$cyl==4,], aes(cyl))+geom_bar()
levels(mtcars[!mtcars$cyl==4,])
This shows my problem. Because no counts are available for factorlevel '4',
the label 4 dissapears from the plot. However, I
