smoothScatter plot
Hi, I want to make a plot similar to sm1 (attached). The code I tried is: dcols <- densCols(x,y)
smoothScatter(x,y, col = dcols, pch=20,xlab="A",ylab="B")
abline(h=0, col="red")
But it turned out to be s1 (attached) with big dots. I was wondering if anything wrong with my code. Thanks,Zhengyu

Add text A, B, C and D on multiple ordered plot
Dear list,
Is there a elegant way to name multiple ordered plot as A, B, C and D?
Just put A, B, C and D on the top left corner of each plot.
Usually I do it in Illustrator, but I think in R should there is a way.
Could you please provide a example?
Thank you very much in advance.

Simple reshape problem I am completely missing
I seem to be doing something really stupid or missing something really obvious but what?
I have a simple three column data.frame that I would like to reshape to wide preferably using reshape2.
An example from http://stackoverflow.com/questions/9617348/reshape-three-column-data-frame-to-matrix looked perfect except I wanted a data frame but it seemed okay. I just changed acast to dcast and it

R Commander - Time Series
Hello all,
I'm just starting to learn R and I heard a good way of doing that was R
Commander. For my work I use a lot of time series, so I installed (and
loaded) R Commander with epack.
When I go to Ts-Models, after loading my data, I click on ARIMA Models tab.
I load my variable D1 Ln Demand (1st differenced ln demand). I set my
regular and seasonal p d q settings hit run and I get:

Hi Keith,,

Axes value format
Hi all,
I have some graphs where the values on the X and Y axes are by default
in exponent form like 2e+05 or 1.0e+07. Is it possible to make them in
a more readable form like 10M for 1.0e+07 or 200K for 2e+05?
Thanks and Regards,

R-help Digest, Vol 124, Issue 12
Folks,
Sorry for butting in here. I ran the code from John Kane below and it worked fine.
I did however get a deprecation message suggesting the use of ggpairs from the GGally package to make this chart.
Unfortunately I haven't found the correct incantation to get the diagonal to display the density plots using the "diag" parameter.
Any suggestions?

plotting two histograms on one plot with hist function
I would like to plot two data sets (frequency (y-axis) of mean values for 0-1(x=axis)) on a single histogram for comparison. The hist() only allow the overlay of two histograms, and although barplot() allows beside=TRUE, it does not show frequency values (like hist) but rather all of the values. Is there any way that I can use the hist() to plot two data sets similar to the barplot(). Any help or
