Monte Carlo Simulation
Hello, R friends...
I am very new to R, and I need some help. I am trying to construct a simulation for my dissertation.
I need to create 1000 datasets of 1000 subjects with the following variables...
Treatment variable - Drawn from a binomial distribution (1 run, prob=.13)
Covariate 1 - Drawn from a normal distribution (mean=100, sd=16)
Covariate 2 - Drawn from a normal distribution (mean=200, sd=9)
Covariates 1 and 2 need to be correlated (say, r=.80)
Covariate 3 - Drawn from a binomial distribution (1 run, prob=.5)
Cov...

Different gridlines per panel in xyplot
In the example R script below, horizontal gray gridlines are drawn at y
coordinates where the points are drawn with the code:
panel.abline(h=y, v=xScale, col.line="gray")
How do I change this so that the horizontal gray gridlines are drawn at y
coordinates where the y labels are drawn? The challenge is that each panel
has different y-ranges (in my rea...

symbols: zero radius circles are drawn.
Hi,
I don't think this is a bug, but I thought I'd mention it in case
others think it is not correct... I guess it is probably just a
rounding error.
If I use symbols() to draw some circles, any circle with radius of
zero gets drawn as a small circle. As an example:
postscript(file="test.ps")
symbols(1:9, rep(2,9),
circles=seq(from=0.05, to=0.0, length=9),
inches=FALSE, xlim=c(0, 10), ylim=c(1,3))
dev.off()
The rightmost circle should be of radius 0, but looking at the plot it is
drawn bigger tha...

lattice: axes drawn when relation='free' or relation='sliced' but not when relation='same'
...anel. Instead, I get ticks on the left-hand side of only the
panels in the leftmost column, and labels only on the right-hand side of the rightmost column. What can account for that?
What seems especially peculiar is that when I change relation to 'sliced' or 'free', the axes are drawn as I want them to be drawn.
The data that I'm plotting are numeric and range from -.3 to 1.9. I'm using R 2.6.1 and lattice 0.17-2 on Windows XP.
Thank you,

Side by side strip charts
Hi,
I'm looking for some ideas on how to reproduce the attached image in R.
There are three samples, each of size n = 10. The first is drawn from a
normal distribution with mean 60 and standard deviation 3. The second is
drawn from a normal distribution with mean 65 and standard deviation 3. The
third is drawn from a normal distribution with mean 70 and standard
deviation 3.

Plots not drawn with buffered Cairo 1.12
Hi!
On Fedora 18 [1] and Arch Linux [2], using R 2.15.2, X11 plots are not
drawn (i.e. the window stays blank) when using X11.options(type="cairo")
and X11.options(type="dbcairo"). They are correctly drawn when using
X11.options(type="nbcairo") and X11.options(type="xlib"), or after
resizing the X11 window.
The bug happens with Cairo 1.1...

cvs010626 flickering borders before main window drawn
...showing up in cvs010626.
Again the same VB3 application.
The splash screen appears and the main window (which consists
only of a bunch of buttons) is started to be prepared.
In a flickering way many frames or borders appear (empty)
and when finally the splash screen disappears the main window gets
drawn correctly. Then the problem does not appear again during
the same session.
Normally the main window is supposed to appear after the
splash screen is already destroyed. And so it was until
wine010510.tar.gz. I guess that this is still work in progress.
I'm not too much bothered but if the screen...

lattice xyplot: plot multiple lines with different colors
Hi everyone,
I am using the lattice package to plot some simulation results, by using
the function xyplot(). However, I cannot find a way to plot multiple
lines within the same xyplot and to have each of the lines be drawn in a
different color.
This is what I am currently doing:
xyplot(a + b + c ~ x, my_data, panel = panel.lines)
but, of course, all lines are drawn in the same color.
What I would prefer, would be to first print a single line in an xyplot
and then add a new line, and so on (since I want to dyna...

draw borders of bars inside of the rectangles in a barplot
Dear R-users,
I want to draw a barplot with beside=TRUE.
One halve of the bars are drawn with a border, while the other halve are drawn without a border (i.e. filled bars vs. non-filled bars next to each other).
Because borders are drawn around the bars, doing this leads to one halve of the bars being wider than the other halve, expanding across the 0-point of the y-axis.
This problem...

several regression lines in panel of xyplot (trellis graphics)
Dear r-help,
I need to draw xyplot() graphs with several regression lines:
one line for the whole range of x (the variable on the horizontal
axis) and two additional lines for subranges of x.
Is it possible to make first regression line (panel.lmline(x,y,...);)
to be drawn on the whole graph
and regression lines of the subsets to be drawn only over their subsets?
I have defined
plot.panel=function(x,y,...){
panel.xyplot(x,y,...);
panel.lmline(x,y,...);
panel.lmline(x[1:9],y[1:9],...);
panel.lmline(x[10:23],y[10:23],...);
panel.grid(h=-1,v=-1,...);

Box around legends (and postscript?)
...lame?) question. I have noted that when I produce a
graph with multiple plots (e.g. 2x2 plots on the graphics device)
where each plot has multiple series and a legend with reasonable
amounts of text describing the series, the right hand side of the box
surrounding the legend always seems to be drawn through the legend
text when I write the output to a postscript file. The image
displayed by the x11 device on screen seems fine, with the legend
box drawn neatly around the legend text. I have tried altering the
character size and location of the legend text inside the legend
function (cex...

barplot default colors
...I should think that most of the time when people draw barplots,
they want the bars to be in the same color. (At least that's what I'd
expect. The first time I used barplot() in R, I was shocked to see the
colors.) As an example, one example in ?layout draws a scatterplot with
histograms drawn on the margins. The histograms were drawn by barplot(),
and, IMHO, look rather hideous in the colors.

dendrogram plot does not draw long labels ?
Hello,
It seems that the plot function for dendrograms does not draw labels when
they are too long.
> hc <- hclust(dist(USArrests), "ave")
> dend1 <- as.dendrogram(hc)
> dend2 <- cut(dend1, h=70)
> dd <- dend2$lower[[1]]
> plot(dd) # first label is drawn
> attr(dd[[1]], "label") <- "aaaaaaaaaaaaaaaaaa"
> plot(dd) # first label is NOT drawn
Is this expected ?
Is it possible to force the drawing ?
Thank you,

Connect lines in a dot plot on a subject-by-subject basis
...up to five observations. The first five columns of mydata give the time of observation, columns 6-10 give the values at each time point. Some subjects have
all data, some are missing values.
The code I wrote to draw the plot is listed below. If you run the code you will see that (1) The few lines drawn are not drawn on a subject-by-subject basis, (2) not all lines are drawn.
I hope someone can help me fix my code
