qplot of ggplot package how to plot different size according to the values and not to the weights?
I have the following Data structure
$ step45 : Factor w/ 2 levels
$ obserror : num 6.2 6.2 5.6 6.6 6.6 ...
$ Mon : num 2.2 2.0 1.0 3.2 2.0 ...
$ inc.comp : num 4 5 2 5 5 5 5 5 4 4 ...
all I wanted to do is plotting Mon against obserror, the colors should
be by step45 and the size of the symbol should be according to inc.comp
so I did this:

qplot error -
Dear friends, I'm on windows, R 2.15.1 -
library(ggplot2)
#compiled under 2.15.2
qplot(mpg, wt, data=mtcars, colour=cyl) # directly from the qplot help
Error in rename(x, .base_to_ggplot, warn_missing = FALSE) :
could not find function "revalue"
Is that due to a .1 lack in R
All the best

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)

Boxplot BUT with Mean, SD, Max & Min ?
People,
It appears that there is no way of getting Boxplots to plot using Mean,
SD, Max & Min - is there something else that would do what I want? I
couldn't find it . .
Thanks,
Phil.

ggplot2: changing default colors of boxplot
Hi,
I wanted to change the default colors appearing in boxplot. For example, the
following code (from the package/documentation):
===========
library(ggplot2)
p <- ggplot(mtcars, aes(factor(cyl), mpg))
p + geom_boxplot(aes(fill = factor(am)))
===========
Gives the default colors. What do I need to do to modify this so that:
1. Change the colors from green and red to blue and black

connecting boxplots
Hii,
I created some boxplots with this commands:
x <-read.table(file="test.txt")
x$group <- rep(1:8, each=5)
boxplot(V3~gruppe, data=x)
Now, I will connect the boxplots to each other to the min, max and median
values.
Can anybody help me how to do it ?
greetings,

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

ggplot2 boxplot: horizontal, univariate
In ggplot2, I would like to make a boxplot that has the following properties:
(1) Contrary to default, the meaningful axis should be the horizontal axis.
Lattice does this, for instance, by
library(lattice);bwplot(~mtcars$mpg)
(2) It is *univariate*, i.e., of a single vector, say mtcars$mpg. I do not wish to make separate plots for the different values of mtcars$cyl.

how to plot a graph with different pch
I am trying to plot a graph but the points on the graph should be
different symbols and colors. It should represent what is in the legend.
I tried using the points command but this does not work. Is there
another command in R that would allow me to use different symbols and
colors for the points?
Thank you kindly.

bottom legends in ggplot2 ?
Has anyone had success with producing legends to a qplot graph such that the legend is placed on the bottom, under the abcissa rather than to the right hand side ?
The following doesn't move the legend:
library(ggplot2)
qplot(mpg, wt, data=mtcars, colour=cyl, gpar(legend.position="bottom") )
I am using ggplot2_0.8.2.

Print grid/ggplot to a metafile
Dear UseRs called Hadley, or Paul,
I am trying to print an edited ggplot2/grid graphics to a metafile. With the
commented line below it works, but when I edit the plot by uncommenting the
line, it fails, because it's illegal to have 2 graphics in a metafile. It
works with pdf, but even then I get two plots, which is a nuisance.
I found a workaround by using windows(); savePlot, but it only

change order of plot panels in faceted ggplot/qplot
Hi,
I have a 5-paneled figure that i made using the facet function in
qplot (ggplot). I've managed to arrange the panels into two rows/
three columns, but for the sake of easy visual comparisons between
panels in my particular dataset, I want to have the two plots on the
bottom align on the right hand side of the figure instead of the left.
Here's an example:

two-way categorical anova post-hoc data extraction
Hi list,
I have a question regarding post-hoc extraction of data from a two-way categorical anova.
I have a categorical anova of this form:
width ~ steepness + patchiness (4 steepness levels, 4 patchiness levels)
This simple setup answers if for the widths I collected across different levels of steepness and patchiness significant differences can be found. Is there a way to look at these

ggplot, qplot: alpha channel for colors corresponding to factor
Hi,
I have a qplot like the one in the minimal example below, except I
also have faceting like this:
qplot(jitter(Goodall),jitter(Better.adapt),colour=Second.adapt,facets=~Pol,data=d1)
and with the real data I get quite a lot of overplotting, so I would
like to add an alpha channel.
In addition, I would like to be able to control which colors are used
for each value of Second.adapt (which
