Hello everyone!!
I have written a function in R and need to call it more than once say M
times then take an average of my output. How would I tell R to automatically
call my function many times instead of just the once?
The natural way will depend on what you're trying to
gsub((.*)(.{2}),\\1/\\2,dates)

Try this:

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)

e.g. I have a big data set called combined, and then a small sample of

combined to create a new smaller data set and store it into a new object.

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...)

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:
Dear Gabor Csardi,
Thanks. The problem is now resolved.
No wonder, writing computer programs is not just typing in random words
and let the computer figure
out what you are trying to do. At least not yet.
Apart from typo errors like wri before write... and lecompose instead
of decompose,
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
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.

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,
1 - 100 of 162 matches
