Hello,
I am trying to extract a subset of a dataframe A (2 columns) by
extracting all entries in A (several repeated entries) that match
dataframe B in both columns. For example, part of A and B are shown
below.
The following does not seem to work correctly. This only seems to select
on
A[with(A, paste(C1, C2, sep = \r)) %in% with(B, paste(C1, C2, sep=\r)), ]
C1 C2
19 A 200
(Using sep = \r is perhaps a little too cautious.)

Please note that the case of characters is important in R. Hence True
differs from TRUE. You need to use REML = TRUE instead of REML = True!
The only valid logical values are TRUE, FALSE, T and F. But I recommend
to use only TRUE and FALSE. Because you can overwrite T and F. You could

I will compile an old version tomorrow and make it available
From the help for panel.levelplot in the section on 'col.regions':
the exact number being one

The second part was somewhat speculation on my part,

Have you contacted the author of eps2pgf?
A while back I had a plot generated by R that produced an error in eps2pgf, I
sent a copy of it to the author of eps2pgf and within a couple of days he sent
me a new version that worked with my plot. But he cannot fix problems that he
does not know
Max,
Since the dataset is sorted by ID, with ties broken by N, the following
should do it and do it quickly. It grabs the rows just before ID
changes.
with(data, data[ c(ID[-1] != ID[-length(ID)], TRUE),, drop=FALSE])
ID Type N

Hi,
I'm trying to figure out how to use lme() for analyzing a split-plot
experiment. I've been looking at the examples from the 'R Book',
those are nested but with only one factor at the whole-plot level, my
test is 2^2 at the whole-plot level, with a single many level factor
at the sub-plot
Hi All,
I have microarray data that does not come in a CEL file. Currently it is in
the form of columns = individual samples and rows = individual probes. There
are about 79 columns and it is in a tab delimited text file. Is there a way to
convert this file into an AffyBatch so that I can
No I haven't done that, and of course, you're right. I'll do that. But I
still wish there was a way to generate PGF code directly.

In fact, eps2pgf worked fine in my example after building it from svn.

Hi:
Here is simplified example of what I am having trouble with:
I want to set the gray shade of the background of each panel of a
xyplot with its mean.
My aim is to be able to compare at a glance which panel has the highest mean.
But, in order to achieve this I have to normalize the means
