side by side plot of Histogram and densityplot
Using "par" seems easily put a "hist" and a density side by side on the same output window.
I would like to use some features in "histogram" from Lattice, but how can I put
"histogram" and "densityplot" side by side on the same graph?
Thank you

Help in Overlaying of 2 Plots on the same Device.
I'm trying to overlay a density plot on a previously plotted histogram. However, i need to use the same axis as of the 1st(histogram) plot to plot the second. My second plot is creating its own axis and causing my plot to extend the entire histogram instead of getting a subplot on a portion of the histogram. I tried 'fig' and 'new' parameters with no luck.
Thanks in advance.

Controlling size of boxplot when it is added in a plot
Greetings,
I am trying to add a boxplot to the bottom of a histogram, right
between the histogram bars and the x axis. Here is the code I am
using at the moment (the par line is probably not relevant for our
discussion):
hs <- hist(x, breaks = 20, plot = F)
par(mar = c(3,3,2,1))
hist(x, breaks = 20, main = NULL, ylim = c(-2, max(hs$counts)))
boxplot(x, horizontal = T, axes = T, add =

[FORGED] Different results based on the order of arguments to par
Paul,
I was trying to make a minimal self contained example, but I guess I
went too far on the minimizing. The original problem came from code
more like:
library(TeachingDemos)
hist(rexp(1000), main='')
abline( v=1, col='red')
sp.par <- subplot(hist(rnorm(100), main=''), x='topright')
op <- par(sp.par[c('usr', 'plt')])
abline(v=0,

Arrange histogram
The data set has a number of variables each of which is classified into two groups.
For each variable of each group, I need to create a histogram. All the histograms are to be lined up into a file that looks like
group1 group2
Variable 1 Histogram histogram
Variable 2 Histogram histogram

Can you give me a hint as to what

Different results based on the order of arguments to par
I ran into this issue when trying to modify a subplot (subplot
function in the TeachingDemos package), but here is a more minimal
example of the issue (I don't know that it is serious enough to call a
bug):
This code works how I expect:
dev.new()
hist(rexp(100))
par(plt=c(0.5,0.9,0.5,0.77), usr=c(0,1,0,1))
box() # show new plt region
points(c(0,1), c(0,1), pch=16, col='red', cex=3)

histogram for integer data
hi,
library(lattice)
x<-c(-1,-1,-1,0,0,0,0,1,1,2)
rng<-range(x)
histogram(x,endpoints=c(rng[1]-0.5,rng[2]+0.5),nint=length(unique(x)))
instead of contiguous bins, i'd like spaces between them to indicate
that the data is discrete, or even better, line segments positioned at
integer values.
i know how to do this with plot, but i need it with histogram, so that

Trouble with drplot
Hi, I am a newbie with R, so I hope my question isn't too stupid. I am trying to generate dose-response curves using the "drfit" package. I have formatted my CSV files to the correct format, and have no trouble running drfit to get a summary of my data. The problem is that when I try to use "drplot" to graph my data I get an error. The message is:

graphics and 'layout' question
Hello,
I got stuck with a graphics question: I've 3 figures that I present on a single page (window) via 'layout'. The layout is
layout(matrix(c(1,1,2,3), 2, 2, byrow=TRUE));
so that the frst plot spans the both columns in row one. Now I'd like to magnify the fist figure so that it takes 20% more vertical space (i.e. more space for the y-axis). How would I do this in R?

RandomForest question
Hello,
I'm trying to find out the optimal number of splits (mtry parameter) for a randomForest classification. The classification is binary and there are 32 explanatory variables (mostly factors with each up to 4 levels but also some numeric variables) and 575 cases.
I've seen that although there are only 32 explanatory variables the best classification performance is reached when

Subplot.
Hello All,
I wanted to do many plots (in my case, wanted to get 6 histograms) on the
same figure. Is there a method in R that analogous to 'subplot' in MATLAB?
Any help will be very much appreciated.

overlay histograms on map at map coordinates
Hi all,
I'm trying to visualize animal movement data characteristics
spatiotemporally by overlaying many different histograms on a map. I
want the histograms to be plotted at coordinates in the map that
matches a region they describe. If I was just doing this once, I'd
fiddle in Illustrator after R and avoid the headache. But I'll be
doing it many many times so it seems

splitting very long character string
Hello,
I've a very long character array (>500k characters) that need to split by '\n' resulting in an array of about 60k numbers. The help on strsplit says to use perl=TRUE to get better formance, but still it takes several minutes to split this string.
The massive string is the return value of a call to xmlElementsByTagName from the XML library and looks like this:

pictex graphics device and color
Is the pictex graphics device known not to support color?
In R 2.0.1 Patched (2004-11-17), it produced very pretty output:
## pictex(file = "modern-metatheonomy.tex", bg = "transparent");
## plotData(data);
## dev.off()
... but it appears to have ignored all color information.

question: randomization t-test function already defined in R?
Dear R Users,
I am hoping you can help me.
I have received code from a colleague who uses Matlab. I need to
translate it into R.
I am wondering if there is a randomization t-test (from non-parametric
statistics) function already defined in R.
(In Matlab the function is randtest.m.)
