Using ggplot2 I need to move the location of legend to on the plot
Thanks again for the hints about adding the vertical line to the hist plot and in ggplot. That worked great.
Based on that advice I've been flipping through the ggplot2 doc and ggplot-static\index.html webpage more looking for the answer to the next question.
Unfortunately, I haven't stumbled on a description of how to move around the location of the legend.

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?

Adding vertical line to histogram and qplot "stacked" plot
R-users it appears I am leaning on your knowledge once again. Is there any way to add a vertical line to a histogram and qplot "stacked" plot? Here is my current attempt:

ggplot qplot bar removing bars when truncating scale
I'm having problems with this example, it is posted with reproduceable code
below, both with the normal 0-6 scale and the desired 3-6 scale (with bars
removed). How can I get the graph to have the desired 3-6 scale without
removing the bars. Thanks!

Changing histogram stack in qplot
I've been using qplot pretty successfully to generate stacked histograms. However, it appears that I need to tweak the colors a little.
I've got three temperature variables (characters not numeric) and I need to change from the default qplot colors to the following:
Low = Blue
Middle = black
High = Red
Here is pseudo code of what I have currently:qplot(Run, data = TestData, breaks =

multiple qplot histograms in one plot
Hi,
I wish to plot multiple histograms(representing different data so different
range along xaxis but y axis is the same) horizontally in ggplot2. I'd like
it to look like facets. Is this possible?

ggplot2 histograms... a subtle error found
Hello all,
I have a peculiar and particular bug that I stumbled across with
ggplot2. I cannot seem to replicate it with anything other than my specific
data set.
Here is the problem:
- when I try to plot a histogram, allowing for ggplot2 to decide the
binwidths itself, I get the following error:
- stat_bin: binwidth defaulted to range/30. Use 'binwidth = x' to

ggplot2 histograms
Hi
With ggplot2 I can very easily create beautiful histograms but I would like to put two histograms on the same plot. The histograms may be over-lapping.
When they are overlapping the bars are shown on top of each other (so that the overall height is the sum of the two). Is there any way to get them to display overlapping (with smaller value in front, larger value behind) so that the overall

ggplot2 Histogram with density curve

on top of a histogram.
Here are the two graphs that I created.

ggplot2 legend for vertical lines
Dear all,
The following example code produces a graph with ggplot2, to which I
add several vertical lines of arbitrary colors. I am not satisfied
with the legend: it automatically adds some vertical lines which I'd
rather not see (they confuse the reader rather than add information
in this case).

R Stacked Histogram
I've seen this asked, but never fully answered.
Is it possible to plot stacked histograms in R?
I have four data sets that I would like to show combined vertically in histogram format.
Is this possible?
Thank you for any feedback you can provide.
P.S. I know I can show the four sets side by side, but I want to combine them, but still uniquely identify each. Thanks again.

jpeg() creating empty files with qplot() in a loop

I'm stuck with a strange issue with writing jpegs of plots to a folder
in a loop.
This works:

But if I use qplot to generate the plot (which is my aim):

ggplot2 legend problem
I'm trying to overlay two histograms using transparency to enable viewing of

want. However I'm having a problem generating the legend coloring
appropriate to each distribution in the plot.
Here is a test case to show my best (failed) effort so far:

Unable to run smoother in qplot() or ggplot() - complains about knots
