HMisc describe -- error with dates
Hello,
I am trying to use HMisc describe on a data frame. I have specified certain
variables as dates using, for example:
df1$aidsdate <- dates(aidsdate,format="day.mon.year", origin=c(month = 1,
day = 1, year = 1960))
When I use describe on the dataframe I get this error:
Error in Ops.dates(weights, x) : * not defined for chron objects
Has anyone had this problem? I had

confidence-intervals in dotchart
My earlier posting should have said "dotchart", not "barchart".
1) How does one show confidence-intervals in a "dotchart" and use rownames
for labels on the y-axes? I have looked at "plotCI" in "gregmisc" package .
But it does not seem to produce something like a dotchart. The statistic,
error, upper-bound, and lower-bound are in a

POSIXct vs Dates
I noticed the addition of the Dates class for dates without times, in R
1.9. I am making extensive use of POSIXct at present and would like to
know whether it is worth changing to Dates. What are a few of the
trade-offs?
Thanks,
Frank

mailing list for basic questions - preliminary sum up
Dear R-user,
I already received quite a lot of replies to this mail and like to do a
preliminary sum up.
A few were sceptical about the use of such a beginner mailing list.
The arguments were that people starting with R will only stay subscribed for
a short time
until they reached the R-help "level" and therefore only beginner will teach
beginner how to
use R.
But as far

Stepwise regression and PLS
Dear all,
I am a newcomer to R. I intend to using R to do stepwise regression and
PLS with a data set (a 55x20 matrix, with one dependent and 19
independent variable). Based on the same data set, I have done the same
work using SPSS and SAS. However, there is much difference between the
results obtained by R and SPSS or SAS.
In the case of stepwise, SPSS gave out a model with 4 independent

FDA and ICH Compliance of R
Does anybody know if R is FDA or ICH (or EMEA...) compliant? AFAIK S-Plus
is but that means nothing...

R: Including R plots in a Microsoft Word document
Greetings List,
I am conducting some large simulations using R. As a result, I get many plots but I'm having some trouble with including some of them in a Microsoft Word document. Can any one tell me the easiest method of having copies of the R-graphs in the Word documents?
Best regards

PlotMoth Refusing to Draw xlab
Occasionally I have had plotmath refuse to draw x-axis labels. This has happened when the label, created using expression(paste( ) ) as below, could be drawn easily in the available space. I have not reproduced that, but the following example with a clearly overly long label results in no xlab at all. I hoped that at least a truncated label would be plotted. This is probably related to my

The old Fortran underscore problem
I have dealt with this on so many platforms in
the past that I should know the answer by now.
I looked in V&R S Programming, R manuals and FAQ
and still can't find the answer.
In the Hmisc library I used the R scripts to build
the package, which creates Hmisc.so. I have
library.dynam('Hmisc', ...) in the .First.lib.
When doing library(Hmisc) I get

Wish list
Kevin,
I was glad to see your list. Some of the items were reasons for creating
some of the functions in Hmisc. summarize and mApply in conjunction with
llist handle labeling of output - this is actually quite tricky and the
Hmisc solution isn't perfect. Dropping unused factor levels by default
(with easy override) is an old battle and I agree with you completely that
for everyday data
