3d Map with bars
Apologies in advance for the question. I am trying to draw a map of the US
as a surface plot so that I would be able to drop bars on the different
states (something like Uwe Ligges' scatterplot3d example 4). I am not sure
where to start looking for such a beast. If anyone has any pointers,
ideas, I will be grateful.
TIA,

A suggestion regarding multiple replies
Please don't take this the wrong way. There are a lot of extremely helpful
people who subscribe to r-help.
I was wondering if it is time to adopt a strategy a-la Splus help whereby
people reply to the author and the author summarizes all the replies?
Just a thought and have a good weekend.

using the pfe editor with R 1.1.3 under windows 2000
I am in the process of setting up R1.3.1 on a new computer running windows
2000. I am having problems running the PFE text editor simultaneously
within R for editing functions and outside R for editing
ordinary text files. The PFE editor behaves as I expected, if it is opened
in R AND but no other PFE window is open outside R. Similarly, it also
works fine if I am editing a text file outside

axis() color from 1.5.1 to 1.6.1
I see that the definition of axis() has changed from 1.5.1 to 1.6.1 (as
mentioned in the news file for 1.6.0). Axis now has a color argument to
change it's color. However, the following command worked in 1.5.1:
> axis(1, at = c(0.1, 0.2, 1, 5, 10), fg= gray(0.7), cex.axis = 0.8,
col.axis= "red") #plot the axis in gray with annotations in red.

R-release dynamic load problem on HPUX10.20
Hello,
I just pulled the patched release:
R-release Version 1.0.0 Patched (March 19, 2000), on HPUX10.2
I am having dynamic library load problems. I configured with:
./configure --prefix=/home/absd00t/local --with-readline --with-x
After changing etc/Makeconf to take -lblas out of libs (the blas
library provided by the system is not a shared library), system was
built without any interruptions.

Bug in Plot.table?
While plotting a table using plot(table), I am not able to suppress the
axes with axes = FALSE. Am I missing something or is it a bug?
For example:
> x <- c(rep(0, 7), rep(1, 4), rep(5, 3), rep(6, 4), rep(8, 10))
> table(x)
> plot(table(x), axes = FALSE) #does not suppress the
axes
> plot(table(x), frame.plot= FALSE, axes = FASLE) #deliberate spelling

strptime
Delving into the murky world of dates and times I found this:
dates <- c("02/27/92", "02/27/92", "01/14/92", "02/28/92", "02/01/92")
> times <- c("23:03:20", "22:29:56", "01:03:30", "18:21:03", "16:56:26")

Fisher's Exact Test
Appology in advance if this has been asked and answered. I am getting different
answers using Fisher's exact test in the package ctest. For example:

Wrong text() adjustment with (math)expression and "\n" (PR#299)

R-0.65.1 Startup
Dear R users,
I have noticed that my R startup is extremely slow. It takes almost 3
minutes from "double-click" to R prompt. I have been running R-0.64.1 till
recently and it took about 30 sec. I still have access to R-0.64.1. When I
started it up, it took about 25 sec. Can anyone tell me if this is a bug in
R or a problem with my machine?

Problem with diff(strptime(...
Hi all,
I have been chipping away at a problem I encountered in calculating
rates per year from a moderately large data file (46412 rows). When I
ran the following command, I got obviously wrong output:
interval<-
c(NA,as.numeric(diff(
strptime(mkdf$MEAS_DATE,"%d/%m/%Y")))/365.25)
The values in MEAS_DATE looked like this:

Does strptime(...,tz="GMT") do anything?
Hi All
In trying to correlate some tide gauge data I need to deal with varying
timezones. From the documentation on strptime, it seemed that the tz
variable might have some effect on the conversion, but I'm not seeing an
effect.
