The help function in R is just that -- a function -- so you have to
invoke it, e.g., as help(mean) rather than just typing Help. You might
also try help.start() which opens a fuller help system in your

You didn't give much of a description of what sort of numbers you expected

Thanks for your response, John. That was helpful.
I was using Type III from Anova() as a comparison to some results I had
obtained JMP, which I've lost access to and have moved on to R, and I was
confused by the error. Given that I do have a continuous covariate, the
analyses are not likely comp
I noticed about a couple weeks ago that my R start up script starting showing
the below errors, following the line "Type 'q()' to quit R"
Not sure what I did different and so far it hasn't caused major problems but
kind of fear that it will.
Can you please help?
I also posted my Rprofile below.
Hi everyone,
I have a list betaMoments with 2 levels, e.g.
> beta1 = list(
+m = 4,
+v = 5
+)
> beta2 = list(
+m = 6,
+v = 7
+)

> betaMoments[[1]] = beta1
> betaMoments[[2]]

Hello all,
I was trying to create nice tables in HTML on windows and then got to know
about Pander. I have installed Pandoc, devtools, Rtools (which has same
path as of R ) . I have also gone through the depends of Pander and fixed
it all. Still i am not able to install and getting a conflicting e
What does any of this mean?
Can you give a concrete example of the transformation you hope to accomplish?

Hi all,
I am working on an optimization of the svm classification function based on
the package e1071. So far we have not been able to find any dataset that
really slows down the application. However, from R users surveys seem that
svm would be a good function to speed up.
Is there any one working
Hello,
Please read the posting guide: to draw samples from what? A vector?
Matrix? Etc...
Anyway, here it goes. In all cases the result is a list with 4 elements.
# Draw 4 samples of integers from 1 to 10
x <- rep(10, 4)
# without replacement
set.seed(1)
lapply(x, sample, size=6)
# with rep
I used it but still same error.

I would be good if you showed us what you are doing now. There are
ways of drawing samples and storing in a list, but we have to see what
you are trying to accomplish. You could use 'lapply' or do it in a
loop, but the solution would depend on how you are doing things now
and what is the problem
Hi Duncan,
That's right but I want to be able to use this to replace back slashes with
front slashes when I copy and paste file paths. How can I make this work so I
don't get this error?
Thanks.

Stefan, that looks wonderful! I am most certainly going to try to

even download it at this point. Many thanks! But yes, I need the

60% will save me days! If I c
Then don't do that.
write.csv is designed to write a complete matrix or data frame in one call.
Combine your list of matrices into one (e.g. using sapply) and write that in
one call afterward rather than piecewise as you do the calculations.

Hello Jim
thank you so much for your response.
When I use write.csv, on the csv file is saved only the last loop
So when I write
results.matrix <- apply(degree_w(net.static[[i]]), 2, mean)
write.csv(results.matrix, file = "results.csv")
instead of getting a 550 line document with all loop result
What do you mean by "only the last j"? write.csv writes to a file you
specify and I assume that you are changing the file name if you are
making successive writes. You need to provide more detail.

Hello,
Have you tried what I wrote in my last post?
Revised:
# Make a copy first, and operate on the copy.
dep <- departures
names(dep) <- NULL
dep <- data.frame(dep)
