Bug in function boxplot's axis labeling
...e(boot)
boxplot(time ~ poison, poisons, horizontal=TRUE)
The correct labels would be obtained by
boxplot(time ~ poison, poisons, horizontal=TRUE, xlab="time", ylab="poison")

calc.relimp pmvd for US R-user
Dear All:
I am calculating the relative importance of a regressor in a linear model.
Does anyone know how I can obtain/install the 'pmvd' computation type? I am
a US user.

date conversation
Hello,
when I convert a factor like this a=01.10.2009
into a date using b=strptime(a, format="%d. %m. %Y").
It works very well.
But when I try to convert c = 2009/10 into a date using
d=strptime(c, format="%Y/%m")
it doesnt work at all. I get d=NA.
What did I do wrong?
Thank you very much for your help!
best regards

mondate: timeunits="months"

Importing function that is previously imported by other package
...of the packages FrF2 depends on
also imports from utils, including utils::combn.
Shouldn't it be possible to have several packages IMport a function of
the same name without a warning?

subtract a time period from a date
Hello everybody,
how can I reduce e.g. 30 days from a date?
When I do the following "2011-05-01 CEST" -"2011-04-01 CEST" I get:
"Time difference of 30 days"
an thats fine.
But when I try "2011-05-01 CEST" - 30 I get nonsense.
So how can I subtract some days, month or years from a date?
thanking you in anticipation

Or is a chang relative depending on the data?
I didnt get it in manual.

Reason for difference in singular value decomposition produced by function La.svd (via prcomp)?
Dear expeRts,
I have run some simulations under R 2.15.1 on a Mac, and I have rerun a
sample of them under R 3.0.1 on Windows (and also for comparison under
R2.14.1 on Windows). For most cases, I get exactly the same results in
all three runs. However, for those cases that depend on principal
components computed with prcomp, where the particular choice of the
orthogonalization is arbitrary

sysdata.rda vs. rda files in data directory
Dear developeRs,
my package FrF2.catlg128 holds large catalogues and is supposed to gain
additional ones. All the catalogues are intended for the user.
So far, the catalogues were stored in the data directory, and LazyData
was "no". I understand that this is not considered wise any more (if it
ever was), so that I want to change to LazyData "yes" with the next
release

cluster analysis with pairwise data
Hello,
I want to do a cluster analysis with my data. The problem is, that the

I've got a problem concerning the function unique. I have got a

With function subset I chose those shops with more then 10 employee and
store it in data.frame "bigshopdata" with 700 shops.

Anova unbalanced
Hello everybody,
I have got a data set with about 400 companies. Each company has a
score for its enviroment comportment between 0 and 100. These companies
belong to about 15 different countries. I have e.g. 70 companies from
UK and 5 from Luxembourg,- so the data set is pretty unbalanced and I
want to do an ANOVA. Somthing like aov(enviromentscore~country). But the
aov function is just for
