I'm looking at ggplot-static\position_dodge.html
For ggplot(diamonds, aes(x=price, fill=cut)) + geom_bar(position="dodge") , is
it possible to specify the spacing between the dodge'd bin groupings?
That is, I would like for there to be a small separation (horizontal
space) between the "Idea

Hi.
I have two variables, x and y, that are each normally distributed with
mean 0 and have known standard deviations. The variables also have a
known correlation, so I can represent their correlations in a matrix
like so:
a <- array(c(0.3,0.1,0.1,0.2),c(2,2))

Hi,
I have a very basic question on merging two matrices by alternating the
rows. For illustration, assume two matrices -
A looks like:
10 10
10 10
B looks like:
20 20
20 20
How do I combine them such that I get alternating rows from A and B? My
final result should be C which looks like:

Dear R-experts,
I'm having some doubts concernig the scores function of the "outliers"
package. I don´t understand the results when I select the p-value option on
a sample, ie, when I use scores(x,"(method)",1). The help on the function
says that the output are the p-values associatted to the samp

Hi, I have been trying unsuccessfully to plot data using different colors
based on a variable within a subset of an imported file. The file I am
reading is about 2 lines long and has a column (in the example called
FILE) that contains approximately 100 unique entries. I would like to plot a
