The problem is that install.packages() and friends forks R and there is
no way to specify general options to that process (you can do the
configure.{args,vars} but nothing else).
One work-around could be to download the package and install it with R
--vanilla CMD INSTALL from the command line.

Building on Erik's solution and because it would easier to do date
arithmetic..
d1 <- as.character(date)
d1 <- ifelse(nchar(d1)<4, paste(0,d1,sep=""),d1)
d2 <- as.Date(date, "%m%d")

Thanks all! That did it.

The data.frame is constructed by one of the following functions:
funweek <- function(df)
if (length(df$elapsed_time) > 5) {
rv = fitdist(df$elapsed_time,"exp")
rv$year = df$sale_year[1]
rv$sample = df$sale_week[1]
rv$granularity = "week"
rv
}
funmonth <- function(df)

Use write.table() instead.
I thought that I had used write.csv() with an append before but I cannot find
an example. Perhaps append= is not available in write.csv

Thanks! That's much less complicated and does everything I wanted it to do.

Question from an [R] novice...
Hi,
I have a vector of date/times like the one shown below (a truncated
sample of a much longer list...)
> dates[1:4]
[1] "2006-03-16 08:41:00" "2006-03-16 10:28:00" "2006-03-16 11:03:00"
[4] "2006-03-16 11:04:00"
I would like to generate a weekday histogram showing
Out of curiosity, is this a change in 2.11? I'm still runnning 2.10.1,
?write.csv mentions the other options being ignored, but not append. This
might also explain why John Kane believes he has successfully used append
with write.csv in that past.

Actually I have one more question that's somewhat related-- I'm starting out
by importing a .txt file that isn't divided into vectors and is at times
inconsistent with regards to spacing, indents, etc., so I can't rely on
those. It looks something like this:
"Drink=Coffee:Location=Office:Time=M

Hello everybody,
I write my bachelor-work in statistic about "Methods of nonlinear prediction in
time series". I will apply the local linear point forecast (from Yao and Tong
(1994a): Nonparametric method with the kernel function). I couldn`t find a
appropriate package for this method. Have somebo
Never mind, I found the answer to my own question. From the 2.11.0 change
log:
owrite.csv[2] no longer allow 'append' to be changed: as ever,
direct calls to write.table() give more flexibility as well as
more room for error.

Thanks Marc
The next part of the question, though, involves the fact that there is a new
'z' list made in almost every iteration through the ID loop.
I guess there are two parts to the question. First, how would I make a list
containing all the data frames created by a call to rbind? I assume,
Yes, this behavior is new in 2.11.x. From the NEWS file:

more room for error.

Specifically, I have 187 columns in "combined", and "miceSample" only has 4
columns. So the new data frame should have 183 columns.

It's high time for a small, reproducible example. Don't say, "for

That being said, something like

Tal was on the right track, but the function in package zoo that applies
