Two issues with ggplot2 - grid.gedit doesn't work from source file & grid.gedit effects are not preserved
Code for this post is shown below.
Two issues:
(1) grid.gedit doesn't work from source file
Reproduce - copy the code shown below into an R source file, and of course save off in the appropriate location. Then copy the the first line "source("C:/TestCode.R")" into R and run. Notice that you get the following error:Error in editDLfromGPath(gPath, specs, strict, grep,

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:

ddply function nesting problems
While putting my R code into functions, I've encountered a ddply function nesting issue and need a bit of advice on the proper way to fix it.? I've tried several approahces, but neither worked and I need to have the ability to include the "cut", "range", and "fullseq" methods within ddply.? (For a bit of that explanation refer to

A way to "lock down" the order of bars for ggplot "dodged" histogram
It appears that ggplot reorder the data for a "dodged" histogram based on whether or not a specific variable has a value in the first bin.
I would like to be able to absolutely force the order of the variables in the bin. For example, say I have three variables Me, You, and Them.
Me_df<-data.frame(Data = c(1:15), Person = "Me")
You_df<-data.frame(Data = c(10:20),

two plots in qplot
Hello
I simply want to plot two variables against one 'year' variable in
qplot.
Is any way of doing this without reshaping data in long format and using
facet function afterwards?
Thank you

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:

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)

Converting qqplot2 qplot() to grammar?
Hello all,
I've been using the following qplot command:
qplot(pixX,pixY, data=som, geom="tile", fill=rgb) +
scale_fill_identity() + opts(aspect.ratio = .75) + facet_grid(unitX ~ unitY)
Now I would like to convert it into the explicit ggplot grammar, so I
can remove the extras: axes, labels, background, borders, facet labels,
and extra white-space around the plot. (If anyone has

dotplot: character size of labels

Dotchart showing mean and median by group

Plot window - save as Postscript question
R 2.4.0 for Windows
The following plot appears as a squared window (as all r-plots)
Not all subtitles are visible, but all subtitle will appear, when
changing the aspect ratio of the plot window with the mouse to a wide
format.
But does not work when using the save as postscript menu item from the
plot window.
is there any solution for that?

Vertical bars with barchart
Hallo,
What is the right way to get vertical bars in
a barchart?
For instance
barchart(VADeaths,
key=simpleKey(colnames(VADeaths),points=F,rectangles=T))
gives what I need,
only I would like the bars to be vertical.
But
barchart(VADeaths,horizontal=F,
key=simpleKey(colnames(VADeaths),points=F,rectangles=T))
does not give what I need,
and I do not understand how to change the

dotplot: character size of labels (PR#816)
There seems to be a bug in "dotplot" concerning the "cex" parameter. Setting
cex has no effect on the character size of the labels of the points.
This problem was posted to r-help today (Thu, 18 Jan 2001); the solution
given by Brian Ripley (and Uwe Ligges) seems to work for me.

bug/feature with barplot?
I have found a bug/feature with barplot that at least to me shows
undesireable behaviour. When using barplot and plotting fewer
groups/levels/factors(I am unsure what they are called) than the number
of colors stated in a col statement, the colors wrap around such that
the colors are not fixed to one group. This is mostly problematic when
I make R figures using scripts, since I sometimes have

lattice: How to display no box but only a y-axis on the left + Thicker lines
Hi,
I have two somewhat embarassing questions about the lattice-related
plot functions:
1.) How do I make lattice (e.g. barchart) to not draw a box but only a
y-axis on the left hand side so that the plot looks like barplot with
default settings? So that the following two code snippets look more
alike:

Bar widths in barplots don't change
Is the width= parameter in barplot() supposed to work? I couldn't get it to
work in my plot, and even in the example,
data(VADeaths, package = "base")
barplot(VADeaths, width=rep(0.1, 4))
the plot looks identical regardless of what I put in for the width. I looked at
the source for barplot() and it looks like it SHOULD work (but what do I know).
Am I doing something wrong?

Strange error in qplot
Hi all, whenever I try to plot a histogram using qplot() function of
"ggplot2" library, I get error like this :
> qplot(rnorm(1000), geom="histogram", binwidth=0.2, main = "", xlab="",
> ylab="")
Error in scale[[1]] : subscript out of bounds
However if I remove ylab="" argument, then it is working fine. Am I missing
something?
