R help search engine
I recently "discovered" how useful the search engine & keywords portion of
R help can be. I often remember that I could do certain things in R but do
not quite remember the right commands. The keywords by topic section of
the search engine is particularly useful for that. It incorporates
information from installed packages which makes it even more useful.
I just ran into the

multiple rugs on a single plot
Hi
I could only find some discussion on this wrt lattice graphics (which I'm
not using). Apologies if I'm missing something obvious.
I'd like to produce 3 rug plots under a kernel density plot for a
population. The population is subdivided into 3 subpopulations, which I'd
like the rug plots to highlight. Naturally, when I do 3 rug plots, they all
plot over each other.

user coordinates and rug plots in lattice graphics
Dear R list members,
I'd like to produce rug plots at the bottom of panels in a trellis display
(using the lattice package), but par("usr") doesn't return user coordinates
for panels, and consequently rug fails, as the following example (suggested
to me by Georges Monette) illustrates:
> x <- rnorm(50)
> y <- rnorm(50)
> f <-

Problems drawing a colored 'rug' in the Lattice 'densityplot'
Hi All,
I'm trying to add a 'rug' representation of my data to a plot created
with densityplot(). While I can do this in the simple case, I can't do
it properly when I include the "groups" argument. I have an example
below. I am running a reasonably new version of R.

Ask for histogram
Hi,
I use a vector of data to draw the histogram, but it is different from the
graph by SAS. Can you check it for me please?
b is a column vector of 4332
hist(b,probability=T,breaks=30,col='lightblue',ylim=c(0,1))
rug(b)
When I used rug, I find the records are smaller than 4332. I don't know
where I did wrong.
Thanks.

rug() colors
Hello,
I have a simple question on rug().
Currently there is only one color possible for the rug.
Is it possible to plot a the rug with different colors, for each rug item ?
Thx.

How do I add a rug to a 3d 'persp' plot?
Hi all,
I have a (hopefully quick) question. I've got a fascinating set of fitted
surfaces in three dimensions corresponding to local linear multiple
regressions. I'd like to add rugs to the X and Y axes (corresponding to my
independent variables) in order to get a sense for how many data points I'm
working with to graph various portions of the surfaces. The trouble is, I
can't

kernel density to smooth plots
Hi r-sers,
I have a data of relative frequencies for the interval of 0-20, 20-40,...380-400. I would like the two data on the same graph using the same x-axis label. My question is how to get a smooth curve using kernel density code if it possible for this data.

Probable bug in "An Introduction to R" (PR#10777)
Both the document and R itself are at 2.6.2 (2008-02-08). When I run in

axis and tick widths decoupled (especially in rugs!)
Hi!
(a complete newby, but will not give up easily!)
I was wondering if there is any way to decouple the axis and tick mark
widths? As I understand they are both controlled by the lwd setting, and
cannot be controlled independently? For example I might want to create major
and minor ticks, which I now know how to do by superimposing two axes with
different at settings, but what if I also wanted

Adding a Rotated Density Plot to an Existing Plot
Hi
Consider the following graph:
x <- rnorm(1000)
x <- x + exp(-x/2)
layout(matrix(rep(c(1,1,2), 2), 2, 3, byrow=TRUE))
boxplot(x)
rug(jitter(x), side=2)
plot(density(x))
What I would really like to do is to have the density plot rotated by 90
degrees so that I can see it line up with the rug plot on the side axis.
I cant seem to do this. I have seen references to the grid

Lattice densityplot with semitransparent filled regions

I'm doing some graphics for a paper and a need customize such with filled

I need, but I don't solve the problem of use semitransparent filled. Below
a minimal reproducible code. Someone has any idea?

gam plots
Dear R users,
Using the library(mgcv) and running R under MacOSX, I have fitted a
generalised additive model with binomial errors in order to check the
linearity of two continuous variables ap2mm and diffdaysm in a glm:

Dweekm:diffdaysm + ap2mm:Dweekm, binomial)

Two datasets on one histogram
I have two .txt files with lists of generated data I want to plot them on the same histogram. I'm aware of the histbackback function, but that is not really what I am looking for, I just want them on the same histogram but so they are still grouped separately (different colours, different norm curves etc). Does anyone know how to do this? Thank you.

hist, lines, rug
Hello,
I'm trying to plot a historgram with a density plot superimposed:
hist(x, seq(-1, 1, by = 0.1), prob = T, col = "blue")
lines(density(x, bw = 0.1))
rug(x)
I don't want to add rug(x) but the histogram will not be plotted unless
rug(x) is there. It does not work if the "hist" line alone is present.
Can you help?
Thanks,
Kim
