Would like some tips on how to avoid loops as I know they are slow in R
i've got a data frame :

What i'd like is to sum for each value of a, the sum of b and the sum of c
where a equal to or less than (with a distance of 5)
i.e. for row three

Hello, I have a matrix of species abundance with a lot of 0 values. I would
like to plot the species abundance vs date, but I don't want that the 0
values appear as points on my graph. Do you know how I could represent only
non-0 values? Thank you very much

Well the data frame has dimensions 0,0, to start with.
Try dim(rm)
What is "getmeasure" and what is it supposed to do?
# btw rm is NOT a good name since it also is a reserved word in R. It removes
objects.
To create a data.frame of your six vectors why not just say
mydata <- data.frame(V1

Looks like the discussion is no longer about R Style, but S3 vs S4?
To that end, I asked more or less the same question a few weeks ago, arising
from the much the same motivations. The discussion was helpful, here's the

Nope Of course, it was just a copy and paste problem

If the code was as posted, you have entered "<" where you probably
wanted "<-".

The short answer is that you're trying to make a categorical interaction
out of
continuous variables, so that the resulting factors i2 and i3 have 1050 and
7200
levels respectively. (Note to people trying to reproduce this example:
you'll
need library(emdbook); library(bbmle); data(Lily_sum) .

Hello R users,
I've read the posts on this topic, and had a look at the R documentation for
nlme, but I can't seem to make this work. I'd like to be able to fit a mixed
effects model with crossed random effects, but also be able to specify the
covariance matrix structure for the residuals. Here's
My first thought was the odometer() function, which is often useful for
tasks like this. To my surprise it is not a part of the current R.
I wonder why? It shouldn't be an Splus copyright issue as this was a
part of my original S distribution (before Splus even existed), and used
in an exampl

hi, everyone,
do you know if there is a R function that can count the lines of a file
without open it?
something like "wc -l " in Unix.
Thanks,

Instead of giving my own code, it's probably better to look at a
