error bars in lattice xyplot *with groups*
Hi all,
I'm trying to plot error bars in a lattice plot generated with xyplot. Deepayan
Sarkar has provided a very useful solution for simple circumstances
(https://stat.ethz.ch/pipermail/r-help/2005-October/081571.html), yet I am
having trouble getting it to work when the "groups" setting is enabled in
xyplot (i.e. multiple lines). To illustrate this, consider the singer data

Lattice xyplot -- footnote font size / mtext
Is there a way of controlling the font size and alignment of a footnote
in an xyplot, or alternatively of using 'mtext' to place a footnote at
the bottom of a graph?

Plotting second axes outside xyplot
Hi all,
I'm trying to find a way to get xyplot to produce a second set of axes outside the right hand side of the graph. This is my progress so far:
EE <- equal.count(ethanol$E, number=9, overlap=1/4)
xyplot(NOx ~ C | EE, data = ethanol,
prepanel = function(x, y) prepanel.loess(x, y, span = 1),
xlab = "Compression Ratio", ylab = "NOx (micrograms/J)",

New Eyes Needed to See Syntax Error
One of many scripts to produce 4 lattice plots on one page keeps throwing
an error. I've tried manipulating the file to eliminate the error, but have
not been able to do so. The error is:

Error in source("bicarb.R") : bicarb.R:15:1: unexpected symbol

Connecting lines across missing data points, xyplot
All,
I have data across 5 time points that I am graphing via xyplot, along with
error bars. For one of the variables I have missing data for two of the
time points. The code below is okay but I can't seem to get the lines to
connect across the missing time points. Does anyone now how to rectify
this?
Cheers,

Multicolor main title in a plot or mtext
Dear R-users, the problem I'm facing today is to write a
multicolor main title in a plot.
I would like to have 3/4 colors to help people in the
audience to visually realize what is what in a 4x2 plot array
On top of each plot I would like to have two lines.
The 1st line will indicate what is plotted
The 2nd line will indicate a a reference
Graphically speaking I would like a result similar

par(las=.) gives wrong "adj" for mtext() (PR#726)
For R Version 1.1.1 and R-devel (Linux)...
Sorry, there's no time to fix myself now
{e.g., after starting a new device} :
par(las=3); plot(1:10); par(las=1) ; mtext("mtext")
Gives a left-adjusted (as for adj = 0) mtext,
even if par("adj") is still 0.5
Note that I'm also not convinced that mtext() should follow par("las")
as it does in the

changing text direction of mtext
Hello,
Does anyone know if it's possible to change the text direction of mtext?
I'd like to use 'mtext(side=2)' but the text should be 'left-to-right'.
I couldn't find an argument for that in the help files.
Thanks for any suggestions
Tobias

Date on x-axis of xyplot
xyplot doesn't seem to want to label my x-axis with dates but instead puts
the day-number for each date.
begdate is the number of days since January 1, 1960 and was initially
created by
library(date)
...
polls$begdate<-mdy.date(begmm,begdd,begyy)
I create a new dataframe (pollstack) which includes begdate. In the process
begdate seems to lose its date attribute so I redo it as:

mtext uses the typographical descender to align text
<>
Hello
One sometimes (quite often really ) marvel at the choice of defaults in
R's graphic engine.
For some obscure reason, mtext uses the typographical descender (bottom
of letters) to align text. That is: "gG" will end up slightly higher
that "GG". Depending on the font, "Q" might end up higher than "O".

adding error bars to lattice plots
Dear R users,
About a year ago Deepayan offered a suggestion to incorporate error bars
into a dotplot using the singer data as an example
<<http://finzi.psych.upenn.edu/R/Rhelp02a/archive/63875.html>>.
When I try to utilize this code with a grouping variable, I get an error
stating that the subscripts argument is missing. I have tried to insert
them in various ways, but cannot

mtext adj= wrong with several las= (PR#7188)
Dear all,
Our quite basic function mtext() does wrong adjustments in some parameter
configurations. This gets obvious when using multi line texts: There is no
way to properly adjust text perpendicular to axis 2, for example.

mtext text size (cex) doesn't match plot
Hi,
I am using mtext instead of the ylab argument in some plots because i
want to move it away from the numbers in the axis. However, the text

cex= and plot(), title(), mtext()
using R 1.2.1 under LinuxPPC, using the default X11 graphics device, i
can't get the cex= argument for plot() and title() to have any effect.
works for text(), though. the text size for plot() and title() _is_
correct if par(cex=size) is called first. oddly, mtext() seems to pay
attention to cex=, but to ignore the value set by par().
for example,

math symbols and text with mtext()
Dear R users,
Two questions:
1) Is there a way to simplify the mtext() line below ?
beta=c(1,-1)
m=5

mtext( bquote(paste( beta == .(paste( "(", paste(beta, collapse=", "), ")" )) )), outer=TRUE,line=-3)
2) How do I get the embedded carriage return "\n" below to work, i.e for the text that follows it to appear on the next line?

losing line of mtext when saving to png format
I have a simple graph (oode below) which looks fine on the screen but when
I save it in png format the title (actually the last mtext line) is cut off.
I am pretty sure that I am doing something very stupid but
other than playing around with the png height and width commands which don't seem to help I have no idea of what to look for.
Any suggestions or cures would be appreciated.
Thanks

Changing mtext direction, or using text for the margin?
Hi all,
I have read through the archives, but can't find a solution to this problem.
I need the text direction on "dependent B", plotted in margin 4, to go
top to bottom (opposite what it is now). Here's some sample code:
#plot with mtext example
par(mgp = c(2,1,0), mfrow=c(2,2), las=1, mar=c(2,2,2,2), omi=
c(0.5,0.2,0,0.2))

Align expression and text in mtext()

As explained in the help files and elsewhere, I understand that the
expression is aligned by the
