Setting the colors of lines in a trellis plot...
With some help from those with expertise on this list, I managed to
produce a plot using trellis that looked like I wanted it to look.
Now, I need to take the same plot and make the lines on it color, but
I want to specify the color for the lines myself.
I've managed to make the key use the colors I want. I've managed to
make the symbols of the actual plot use the colors I want. But I

I assume you want the 'v' variable in panel.abline() to be interpreted
in the context of your x-axis, which here represents a factor
variable. Unless two factor variables have the same

Plotting three time series on the same graph
Dear R Users,
I would like to plot three time series on the same graph, two axis on the
left and one axis on the right.
The time series that I am graphing on the left do not share a similar
scale: one has a range of 1:100 and the other a range of 25000:70000. How
can I display the tick marks for both on the left hand side without
superimposing them, i.e. one set of tick marks in black right

new versions of grid and lattice
Hi
There are new versions of the grid and lattice packages on CRAN:
grid 0.2 and lattice 0.3-0
These packages are still _under development_ (they are in
CRAN/src/contrib/Devel)
There have been some bug fixes and, especially in lattice, there are lots of
new features.
Descriptions of the changes are included below.
If you have any grid code, it may break under the new version because of a

incomplete final line found on <name of my sourced function file>
Dear R-ers,
I hope there is a really simple solution to my problem.
I've written a function that I saved in an .r file. I source this file
in my code. For a while it worked fine. But then when I run the line:
source("F mylineplot.r")
I started getting a warning:
In readLines(file) : incomplete final line found on 'F mylineplot.r'

Barplot+Table
I am trying to automate a report that my company does every couple of years
for the state of Maine. In the past we have used SPSS to run the data and then
used complicated Excel template to make the tables/graphics which we then
imported into Word. Since there are 256 tables/graphics for this report, this
work flow is a little painful. I would like to automate the process and I think

exactly overlaid semi-transparent lines
I'd like to plot n (say n = 10) semi-transparent lines in such a way that if all n happen to exactly overlay each other, the resulting line is completely opaque. In principle, I believe that this is what setting alpha = 1/n should accomplish.
In practice, different values of n produce different results. Consider the following function, which overlays n semi-transparent red lines:

line colors in lattice.xyplot with png device.
Hi,
R is very new for me, so excuse if my questions are too basic...
BTW, are there any forum where new R users could get help without
annoying this huge mailing list ?
In following code, I'd like to choose the color for each of the curve
diplayed.

documentation for 'open': some clarification?
I'm been doing more and more of file text parsing inside R instead of
coping with Perl. For that, I need open a file and read it line-by-line.
I found the documentation for 'open' isn't very clear.
Right now it has

ESRI shapefiles and EMME/2 packages
I just uploaded two packages to CRAN.
shapefiles_0.1.tar.gz - functions to read and write ESRI shapefiles
(including dbfs)
emme2_0.1.tar.gz - functions to read binary data from an EMME/2 databank
data (EMME/2 is a transportation modeling program)
Please let me know if you find any bugs or have some suggestions. Thanks.

and I would like to put the numbers into a vector. Some combination of
tabs and spaces occur between the numbers.
I tried:

maptools: Test if point is in polygon
In R's maptools package, is there a built-in function to test if a

loaded from an ESRI Shapefile. The point's latitude and longitude are
known.
Thank you!

How to enable T.38 between SPA3102 PSTN Line port and ReceiveFAX app ?
Hello,
I've got an analog phone which is currently receiving unsollicited FAX
calls from PSTN.
For learning purpose, I'm preparing an Asterisk/SPA3102 setup that would
let voice calls come in and out and translate incoming FAX calls to TIF
files (forwarded through email)).
My target setup is :
PSTN <-- analog--> SPA3102 Line Port <-- SIP --> Asterisk <-- SIP -->
