Array
Hi there,
Just wondering if anyone has any tips for using arrays?
I am trying to convert the following SAS code to R:
data A2;
set A1;
by subject_id;
retain BX1-BX10 i;
array b(1:10) BX1-BX10 ;
if first.subject_id then do ;
do j=1 to 10;
b(j) = .;
end;
i=1;
end;
b(i) = BX;
i = i+1;
if last.subject_id then

Calculating SD according to groups of rows
*Hi all,
I know this is probably basic, but I have proven to be a slow learner in any
programming language. Anyhow,
how can I calculate the SD for each person in my table? I have two patients
in this R data.frame, 7200 and 23955.
I extracted this from a relational database, but am I better off attempting
to compute SD in SQL, or is this easily accomplished in R?

Creating list or numeric vectors out of selected columns of row oriented data
I am just assuming this can be done, but I have not gotten close to
making it happen. I have a data file with about 1 million rows with
1470 unique subjects. Each row represents a small set of observations
made on a specific date for a single subject. I would like to
transform the data so that I have an R object with a single entry for
each subject and start date and vectors for the

Adding multiple gates/filters in densityplot
Hi R-Users,
I posted this question a while ago on the bioconductor mailing list but got no answers. Maybe here is somebody who might know a solution:
I failed at drawing multiple filters in a densityplot() using the FlowCore/FlowViz packages.
I
found a way to draw multiple filters in xyplot(), using the glpolygon
method within the panel-function, but some similar attempts for

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.

I would do something like

How to generate a figure using par( ) with some densityplot( )'s
Hi Dear R users,
For a pair plotting, usaully we use par( ) function. Apparently it does not work anywhere. I want to have 3 plots in a single figure, like this:
par(mfrow=c(3,1))
densityplot( a)
densityplot(b)
densityplot(c)
But it does not work. How is it possible to have such a figure with densityplot( ) in a single figure?
So many thanks for any help.

small issue with densityplot
Hi folks,
This is really minor but to someone not familiar with the various tentacles of the lmer package it could be really annoying. I was trying to plot the posterior density of the fixed effect parameters of a lmer model,

> densityplot(hr.mcmc, plot.points=F)
There is this error,

no output when run densityplot...
Hi,
I have downloaded a R script from
http://www.wessa.net/rwasp_edauni.wasp#output.
This script produces a densityplot graphic, amongst others, when is
executed from the web page.
However, when I run it in my machine the *densityplot* function produces
any output, I mean a blank graphic.
But, it's interesting if I run the following lines in the R interactive
console:

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?

Several densityplots in single figure

I have created two separate overlapping density plots- see example code

What I wish now to do is combine them into one figure where they sit side

Any help would be great!
many thanks in advance, josh.

How to adjust y-axis when using panel.densityplot within histogram function
Hi
I would like to superimpose group-specific densityplots on top of an overall
histogram using panel.histogram and panel.densityplot. Furthermore, I would
like to automatically adjust the range of the y-axis to take into account
the ranges of both histogram and densityplot. This last part is where I have
a problem. I believe using the prepanel argument of histogram is typically
the way to go,

density plot text
Is there any way of adding text to a density plot? I have had a go using the
text() function but I think the error is because this function doesn't work
with densityplot().
Alternatively, I understand I can achieve pretty much the same result if I
plot a density kernel estimate using plot() (which allows text()), but I do
prefer densityplot().
Also, is it possible to specify the dimensions
