from list to dataframe
I was wondering if someone can help me figure out the following:
I have two patient datasets, ds1 and ds2. ds1 has fields "patid", "date",
and "lab1". ds2 has "patid", "date", and "lab2". I want to find all the
patids that have at least 2 dated records for each lab. I started by
splitting each dataset by patid, to create ds1.list

nlme error on dimensions in multiplication
Hello R users,
When trying to fit a nonlinear mixed model to a respiration time series,
I get the following error message:
Error in recalc.varFunc(object[[i]], conLin) :
dims [product 30] do not match the length of object [34]
In addition: Warning message:
In conLin$Xy * varWeights(object) :

xyplot - help with multiple Y's vs. X of a member data in multiple panels
Dear R experts,
Wish you all a HAPPY NEW YEAR!
How do I go about plotting (using lattice) overlays of an ID (group=ID)
observed, fitted data in each panel of a multiple panel plot (each panel
identified by DS1 + DS2 + DS3)? "x" variable is X1 in the accompanying
section of a dataset. each individual is identified by color and Y's are
identified by "pch" or "lty".

plotting predicted curves with log scale in lattice
Hi,
I was taken off guard by the following behavior in a lattice plot.
I frequently want to add a predicted curve defined at more
points than in the formula expression of xyplot. There have
been numerous examples of how to do this on r-help, but I
still often struggle to make this work. I just realized that
specifying one of the axes on a log scale does not guarantee
that the added data for a

SAS user now converting to R - Help with Transpose
I am just starting to code in R and need some help as I am used to doing this
in SAS.
I have a dataset that looks like this:

O2 7.8 2.6 3.5 2.4
TURB 10.2 14.6 18.5 17.3
and so on with more chemicals....
I would like to transpose my data so that it looks like this:

How to make legend with line+ character
Dear all,
I have a multiline plot with each line labeled with a different letter.
But I'm not able to make the legend display the same kind of pattern
'-a-', instead the letter is overwritten by the line. A simpler legend
with only the letter is not very visible and the pt.bg does nothing with
letters. Any idea?

Node Recovery locks I/O in two-node OCFS2 cluster (DRBD 8.3.8 / Ubuntu 10.10)
I am running a two-node web cluster on OCFS2 via DRBD Primary/Primary
(v8.3.8) and Pacemaker. Everything seems to be working great, except during
testing of hard-boot scenarios.
Whenever I hard-boot one of the nodes, the other node is successfully fenced

Different results for tan(pi/2) and tanpi(1/2)
The same argument would hold for tan(pi/2).
I don't say the result 'NaN' is wrong,
but I thought,
tan(pi*x) and tanpi(x) should give the same result.

inout() in splancs working properly?
I have a problem with function 'inout()' in package 'splancs' on CRAN-R
Version 1.2.3 under FreeBSD4.3-STABLE.
The following script produces and draws points and a polygon-surrounded

zfs object sets and datasets
Hi All,
I am looking at trying to understand the conceptual model of how data is
grouped and partitioned within a storge pool. In looking at the on disk
document that Tabriz sent out a few weeks ago I see that object sets are
the grouping which ZFS uses to group objects that are related.
Specifially to aid in format and layout of like objects in to a set.
So, for example 1 potential object

reshaping issue
Dear R users,
I have a problem with reshaping data. I know such questions have been asked before, but I can't get it right, neither with the reshape function nor with the melt function.
My dataset has about 407 variables and about 48000 cases.
Each case looks as follows:
V1 v2 v3 v4 v5 v6 v7 x1 y1 x2 y2 .... x200 y200

Different results for tan(pi/2) and tanpi(1/2)
As the subject line says, we get different results for tan(pi/2) and
tanpi(1/2), though this should not be the case:
> tan(pi/2)
[1] 1.633124e+16
> tanpi(1/2)
[1] NaN
Warning message:
In tanpi(1/2) : NaNs produced
By redefining tanpi with sinpi and cospi, we can get closer:

> tanpi(c(0, 1/2, 1, 3/2, 2))

2 matrix scatter x [a lot]
Hello,
I'm pretty new to R. Basically, how do I speed up the for loop below. Or
better yet, get rid of the for loop all together.
objective: plot two data sets column against column by index. These data
sets have alot NA's. Some columns are all NA's. I need the plots to overlay.
I don't like the plots in matplot(). Needs to be much faster than the code

Filtering a dataset's columns by another dataset's column names
Hello all,
I hope some of you can come to my rescue, yet again.
I have two genetic datasets, and I want one of the datasets to have only the columns that are in common with the other dataset.
Here is a toy example (my real datasets have hundreds of columns):

Examples of advanced data visualization
Dear R-help,
I am looking for ideas and presentations of new and advanced data visualization
methods. As an example of what I am searching for, the 'Many Eyes' pages at

may provide a good paradigm. I would be interested even if it will not be easy
to implement such examples in R, e.g. because of the interactive nature of these

Poor performance on NFS-exported ZFS volumes
I''m seeing some pretty pitiful performance using ZFS on a NFS server, with a ZFS volume exported (only with rw=host.foo.com,root=host.foo.com opts) and mounted on a Linux host running kernel 2.4.31. This linux kernel I''m working with is limited in that I can only do NFSv2 mounts... irregardless of that aspect, I''m sure something''s amiss.
