Lattice book
Dear all,
I haven't seen this mentioned and presumably Dr. Deepayan Sarkar is
too polite to advertise!
I just received a flyer from Springer: A new book on Lattice released today!!

Sweave, R and complex latex projects
Hello all,
I've been able to use R very successfully to run simple statistics and
generate the plots I require.
I've been evaluating Sweave, and have hit upon a small problem that I
don't seem to be able to workaround. Sweave runs very well for single
file latex documents, but I have a complex thesis made up of several
parts and chapters. These are arranged with a master latex file

Sweave and font problems
Dear All,
Having now successfully started using Sweave, I have just noticed an odd
side effect with fonts.
Using plain LaTeX, I have had no problems using \usepackage{palatino} or
\usepackage{times} and the font correctly changes.
However, once I convert the tex document into Snw, and run it through R
CMD SWEAVE, LaTeX seems to ignore this package directive. The LaTeX log
suggests the font

Aggregation of data frame with calculations of proportions
Dear all,
I have been stuck on this problem, am rather struggling and would
appreciate some advice if anyone can help. I apologise if this is a
bit long-winded, but I've tried to limit it to the bare essentials,
but don't know how to make it more generic!
I have some slightly odd real world data that I'm looking at
representing number of positive diagnoses for different diseases,

R: Query an Access database based on a date attribute
It seems that Access needs that you surround the dates with a # symbol.
You probably need something like.
res <- sqlQuery(channel, "select * from test_table where market = 'atl-bos'
and competitor = 'delta' and dd = #2007-11-20#")
Hope this helps,
Stefano

Produce a multiple formats graphic
Is it possible to produce the same graphic in different formats
in one shot?
Now if I want to produce the same graphic in pdf, ps and jpeg
I run the producing code, but I change the graphic device, and
I choose successively :
pdf(...)
ps(...)
jpeg(...)
So in this case I run the same code 3 times, or I have
to choose a format and use converters...
Is it possible to produce the 3 graphics in once

Density estimation graphs
Dear all,
I'm struggling with a plot and would value any help!
I'm attempting to highlight a histogram and density plot to show a
proportion of cases above a threshold value. I wanted to cross-hatch the
area below the density curve. The breaks and bandwidth are deliberate
integer values because of the type of data I'm looking at.
I've managed to do this, but I don't think it

RODBC and NULL values
Dear All,
Writing sooner than I thought I'd need to.
I'm using R 2.4 on Mac OS X, with RODBC, PostgreSQL 8.1 and Actual's
ODBC driver. I have all my data in Filemaker 8.5, but it is
automatically exported into PostgreSQL for analysis as Filemaker's ODBC
and JDBC access is awful, slow and has a tendency to crash.
I have disability data where for each patient there is a survival

Fwd: Re: Seeking help with trellis: log scales on xyplot
Deepayan:
Sorry for the additional email, but I'm concerned that I wasn't being clear.
In the end, I would like a graphic that portrays my y-values on a log scale in their native data range. That is to say, I would prefer to see the axis labels as 1000 rather than 3 (log10 of 1000).
Thank you for your kind assistance,

Getting estimates from survfit.coxph
Dear all,
I'm having difficulty getting access to data generated by survfit and
print.survfit when they are using with a Cox model (survfit.coxph).
I would like to programmatically access the median survival time for
each strata together with the 95% confidence interval. I can get it on
screen, but can't get to it algorithmically. I found myself examining
the source of print.survfit to

Problem accessing "row number" from subset on a dataframe
I would like to use the "row number" information returned from performing a subset command on a dataframe.
For example, I would like to automatically delete some rows from a dataframe if they match a criteria. Here is my example below.
data(airquality)
names(airquality)
subset(airquality, airquality$Month == 6)
Now how do I delete the row numbers returned automatically?

Export in pdf, png, jpg, eps, etc...
Dear R-users,
I have created a bunch of R scripts that automatically create multiple
plots, all saved in a pdf device. I initially chose pdf output in order
to easily access to multiple plots in a single file.
Now, I am trying to play with different devices, like png or eps and I
realize that the settings I used to have nice plots in a pdf device are
giving awful outputs with the other

modify a data.frame within a function
Hello all,
I'm trying to modify a single column of a data frame to remove randomly half of the values. I want to do it within a function, but can not assign the modified column back into the data frame. It was easy and successful without a function, so I suspect the problem is the call of the single column within the function.

factanal and plotting?
Hi there!
To make a good choice for the estimation of the number of usefull
factors. And I'd like to plot a graph like:
http://de.wikipedia.org/wiki/Bild:Parallelanalyse.jpg
where I don't need the green line (random values).
But with
str(factanal(data, factors=10)) I cannot figure out where I can find the
values for plotting.
Can you please help me in this question?
Thanks,

How to include files in .R?
Hi,
may be its a very simple question, but i did not find any documentation
about a 'include' command or something like this.
I have to set many constants in my R-files and want to move all these to
one file, so that i can reuse it in all other R-files.
Something like
include("~/R/myconstants.R")
kind regards,

larger decimal numbers get rounded ....
Hi,
I am sure there is a reason but ...... why larger decimal numbers get rounded to the nearest integer?
Example:
a <- 3308000.5
a
[1] 3308001
I would like my numbers to be decimals .... since they do represent coordinates and i don't want them rounded .... how can i keep them as they are?
Thanks,

Package Installer Fails in OSX 10.5 Leopard
Hello all,
I apologize in advance if this is not the correct list to post these sorts
of issues. When attempting to install the latest stable build of R (2.6) or
the most recent nightly build from R.research.att.com, the installer
disables the ability to actually install R or any of the other bundled

merge two data sets
I would like to merge ?data1 ?that contains 100 unique ID?s with another
data set ?data 2? with 150 ID?s and the age of those individuals ( the ID in
data1 is a subset of the ID in data 2) I would like to merge these data1
with data2 and have the result of the merge to have the ID ordered as in
data1.
Can this be done in R?

Many thanks for this, and for the other replies received off-list. It is
much appreciated, and confirms that with something as generically
