Cairo on windows
Hi All,
I just installed Cairo on R 2.5.1 on windows XP. My hope was to get to see
the transparency output e.g. http://had.co.nz/ggplot2/stat_smooth.html
ggplot2 - stat_smooth , which I finally managed to do. However, I find the
Cairo device, which I access either through CairoWin() or Cairo(type="win"),
is pretty shaky in a number of respects :

use ggplot in a function to which a column name is given
Hi everyone, Hi ggplot users in particular,
ggplot makes it very easy to plot things given their names when you
use it interactively (and therefore can provide the names of the
columns).
qplot(x,foo,data=A) where A has columns (x,y,foo,bar) for example
but I would like to use this from inside a function to which the name
of the column is given. I cannot find an elegant way to make this

Use cairo fallback resolution greater than 72dpi in cairo_pdf and cairo_ps in grDevices
Dear all,
In grDevices R functions cairo_pdf and cairo_ps it is mentioned that when transparency (alpha channels) are used in vector output, it will rasterize the PDF or postscript exported graph at a resolution of 72 dpi : https://stat.ethz.ch/R-manual/R-devel/library/grDevices/html/cairo.html
You can see the problem if you try

ggplot: problem with fill option in stat_smooth()
Hi all,
I am using ggplot2 and continuing to find it very useful and pretty.
However, I am trying to create some graphics for publication that would be
included in an MS Word document (not my choice!) in Windows Vista.
The problem is that I want to use stat_smooth() to add an fitted linear
model line along with its 95% confidence band, but I cannot seem to get the
confidence band in a format

semi-transparency not supported in devel R? "alpha" cannot be specified in qplot()
Hi dear all,
In my laptop(ubuntu 11.10 64bit), I maintained a released R (2.14) and a
developmental R, I can specify qplot(..., alpha = ) in R 2.14 , but when I
try to use transparency in developmental R, I got a warning message and the
plot is clearly not I want.
minimal example:
> qplot(data = mtcars, x = mpg, y = cyl, alpha = cyl)

Use cairo fallback resolution greater than 72dpi in cairo_pdf and cairo_ps in grDevices
The 'at a minimum' information requested by the posting guide is missing.
According to their documentation the cairo default fallback resolution
is now 300dpi, and when I run your example on Fedora 21 that is what the
emitted postscript says it is.
You can easily alter the R code to set it to something different: see

ggplot2 / reshape / Question on manipulating data
I'm an R newbie but recently discovered the ggplot2 and reshape
packages which seem incredibly useful and much easier to use for a
beginner. Using the data from the IMDB, I'm trying to see how the
average movie rating varies by year. Here is what my data looks like:

qplot (ggplot2) faceting histogram with missing values
Hi,
I've run into a difficulty with qplot function (in the ggplot2
package). I can facet histograms even when the faceting variable
contains missing values, but only so long as the faceting variable is
not a factor.
Example:
y1 <- rnorm(10)
x1 <- c(rep(1,5), rep(2,4), NA)
x2 <- factor(c(rep(1,5), rep(2,4), NA))
library(ggplot2)
qplot(y1, geom = "histogram", facets =

Sweave and ggplot2
Hi all,
I've been trying to run Sweave with R code embedded - using the ggplot2
package and in particular the qplot command. There appears to be a problem
in Sweave not picking up that qplot is a function. Has anybody else tried
to use qplot in Sweave and have you been successful? Any help would be
very much appreciated.
Kind Regards,

I updated/reinstalled ggplot2 and the trouble started...
Hi Ian,
Per your suggestion, I reinstalled R 2.9.0, then
I reinstalled ggplot2 on top. The problem persists.
Here's the what happens after the installation:

Problems with boxplot in ggplot2:qplot
Dataframe closed contains balances of closed accounts: each row has month of
closure (Date-type column month) and latest balance. I would like to plot
by-month distributions of balances. A qplot call below produces several
warnings and no output.
Can anyone help?
Thank you.
PS. A really basic task, very similar to the examples on p. 71 of the

ggplot2 - boxplot of variables / columns
Hi,
ggplot/qplot is great - it has really helped me do some nice things.
However, simple boxplot of different columns/variables is a bit
tricky, because of (i think) qplot's generic Y conditional on X input
form. Se below.
# Some data:
a <- rnorm(100)
b <- rnorm(100,1,2)
c <- rnorm(100,2,0.5)
# normal boxplot of a,b,c
boxplot(a,b,c) # Looks good
library(ggplot2) # loads qqplot2

ggplot2 qplot pch not working anymore
Is there a way to use a continuous variable to pch in qplot? I believe
this worked in previous version. I need to specify certain values of a
shape for particular points so that multiple graphs all show the same
shapes for the same streams. I have gone to the original data and added
a pch column that I would like to use to specify the shapes to pch in
qplot. Any help would be greatly

specifying plot symbol sizes in qplot or ggplot2
Hi.
first things first ... thanks for ggplot2.
Now my question. I'm using qplot to generate a plot as follows where X,Y,Z,
A are columns in a dataframe.
qplot(X, Y, data=XYDATA, color=Z, geom=c("point"), size=A)
This works as expected. Factor A has three levels so there are three sizes
of the point plot symbol. I understand that the factor levels are mapped to
symbol sizes.

Thanks!!
