panel function with barchart (lattice)
Folks at R help,
I can't quite get the panel function to work the way I
want within barchart.
I guess I'm still not understanding how to piece
together multiple panel
arguments, especially when "groups" is specified.
Example: I want to be able to add the value of "yield"
to each section of
each bar in this graph:
barchart(yield ~ variety | site, data = barley,

interrupted Y axis
I did not find an answer to my question after a quick
search using the R
search engine so thought I'd ask away:
Does any know if there's a function exists to create
an interrupted Y axis?
What I mean by interrupted Y axis is that part of the
Y axis has been
removed or excised to permit one to see parts of the
data in more detail.
Perhaps an example will make this clear. Please go to

Numbers as symbols
I want to use question numbers from my survey data
(fake data below) as markers in a scatterplot. I'm
using "as.character" to convert question numbers to
characters. However, plot truncates the 0 (zero) off
of question 10. How can I get the ending zero so I can
add questions 11 - 20?
# Sample code below
Question <- c(1,2,3,4,5,6,7,8,9,10)
Performance <-

.Rprofile and RODBC
Since installing R 2.0 I've had the following 2 issues
I can't find solutions for. I'm using Windows XP.
1) R 1.9 continues to read my .Rprofile file in my
home directory but R 2.0 does not. How do I get R 2.0
to do this?
2) The following function no longer works in R 2.0 but
continues to work in R 1.9:
getExcel <- function (x) {
invisible(require(RODBC))
x <-

comparison operator, decimals, and signif()
Hi, I recently spent quite a bit of time trouble
shooting a function that I had written only to
discover that the problem I was having was with the
comparison operator. I assumed that the following
would return TRUE:
> testMean <- 82.8 + 0.1
> testMean
[1] 82.9
> testMean == 82.9
[1] FALSE
Apparently this has to do with deciml places. Look:
> newTest <- 82.0
> newTest
[1]

Wikis for R
Frank uses the term "hierarchical keyword
organization" which I agree is a good way to organize
a system designed to help users. In fact, this is one
reason why I like the R graphics gallery which allows
one to quickly find a particular type of plot based on
keyword, examine the plot to see if it's close to
what's desired, and then get the detailed code to
examine or modify for
