mean-aggregate – but use unique for factor variables
Hi,
I have a data.frame which I want to aggregate.
There are some grouping variables and some continuous variables for which I would like to have the mean.
However there are also some factor-variables in the data-frame that are not grouping variables and I actually would like to aggregate these variables with the unique() function.
Is that possible with the standard aggregate-function?

In the non linear mixed effects package a groupedData object can be
created to facilitate modeling.
The gD object includes a formula of the form 'response variable' ~
'primary covariate' | 'grouping factor'.
In experiments creating response surfaces there are 2 or more primary
covariates.
Is there any way to use the groupedData() function to include 2 primary

Labeling points with xYplot
Hello R-Users,
I am trying to label points on an xYplot. I can label the points, but
then I lose the error bars. I suspect that I should be using
panel.xYplot rather than panel.xyplot, but that didn't work either...
Can anybody help me out? Example code is below. First xYplot has error
bars, second tries to label the points and the bars disappear.
Thanks,
John

control point size of superscript when labeling axes with title()
Hi-
A journal has asked me to make all of my text annotations on a figure at 10-point size. For the most part this is easy, e.g. by creating figures with:
pdf(..., family='Times', pointsize=10)
But where I have superscripts (or subscripts) in axis labels, the default seems to be to shrink the superscripted text slightly. For example this code:

R help, labeling the tick marks as I want
R help,
I would like to change the labels of my tick marks on the x-axis, and I am
having difficulty understanding how. Basically, my current axis labels
are: 0, 50, 100, 150, 200, and I would like: 1962Q1, 1974Q2, 186Q4, 1999Q2,

With all respect to generality, could you please simply tell me the code to

Decoding subscripts/superscripts from CSVs
Hi,
I have a CSV file with various biological reactions. Subscripts, superscripts,
and italics are encoded in carats, and I was wondering if R can actually
recognize those and print actual superscripts, etc. Here's an example:

Converting to subscripts and superscripts
Hi,
I am reading in a CSV file of chemical reactions where the subscripts and
superscripts are encoded in angle brackets, like below:
2 H<SUP>+</SUP> + 2 O<SUB>2</SUB><SUP>-</SUP>
Is there a way to convert these to actual sub/superscripts and save them in
another excel file? I greatly appreciate the help!
Thanks,

ltext - adding text to each panel from a matrix
Hi all (really probably just Deepayan):
In the plot below I want to add text on either side of each violin plot that
indicates the number of observations that are either positive or negative.
I'm trying to do this with ltext() and I've also monkeyed about with
panel.text(). The code below is generally what I want but my calls to
ltext() are wrong and I'm not sure how to fix them.

Convert string for expression in plot
Hi,
Although I understand how to use expression and paste to add
superscripts and symbols to my graphs, I have a problem with adding
superscripts to an existing string.
For example, I read in the following from a separate file:
25Mg(p,g)
I want to convert that to superscripts etc. (in LaTex format):
$^{25}$Mg(p,$\gamma$)
This needs to then be put into a graph title.
Any ideas? I know that I

I'm doing an analisys about abundance of a planctonic specie in Robinson Crusoe Islan and I am having a hard time just adding the superscripts and the 100 (one hundred) in the measure of abundance.
Perhaps this is so basic to you, but I need to put the real unit of measure. Individuals / 100 cubic meters.

ltext( pos=NULL )
ltext( 0, 0, pos=NULL, label="xxxx")
gives an error message.
The help page of ``ltext'' references to the help page of ``text''
where the default value of pos is set to NULL.
To solve the problem ``ltext'' could be changed:
OLD:
if (!missing(pos))
NEW:
if (!missing(pos) && ! is.null(pos) )

lattice ltext
Dear friends - please give me a hand.
I have a dataset of 40 patients in two groups observed on three
occasions. I only want to plot a line
for each patient in the two groups. I use the ltext function to put the
patient number but fail to make lattice understand the numbers as
unique since apparently it starts all over with 1:20 for each panel
instead of respecting my desires to have 1:20

Properly Parsing Pre-Superscripts & Displaying Them With grid.text

insert a text in panels, always in the same position (lattice, ltext, ?prepanel?)
Dear R-users,
my present problem is related to lattice.
I would like to put some text in each panel, namely a p-value.
I therefore wrote a simple panel function as reported here below.
I'm able to write the value in each panel at the maximum value of y for
each panel,
but this obviously overlay the text to the points.
What I'm looking for is to write the text always in the same
