From the code of legend() the length seems to be hard-wired (seg.len
= 2). You could copy the code and add this "seg.len" as a free
parameter in your own custom function. An alternative is to use the

Hi,
Any R.oo Object must accept no arguments, e.g. Object(). Thus, in

Typically, I would do it this way:

In general, I think you should be able to do:

If you use
url("http://euclid.psych.yorku.ca/SCS/Gallery/Private/langrens.csv";)
then most functions will work, because that creates a connection to read
the URL. Most functions that can read files do it through connections.

Hello,
I am having trouble loading the package candisc onto my R distribution. I am
using 2.7.1-2. I do a "> install.packages("candisc"
and get the following output.
Warning in install.packages("candisc") :
argument 'lib' is missing: using '/usr/local/lib/R/site-library'

Dear R-Helpers:
I'm having a problem getting dates into the correct format. I have a

R has converted my date variables to factors; when I use the as.Date

Thank you very much, Peter. As is often the case, R gave me exactly what I
asked it to give me, but not what I wanted it to give me. :)

I think i might of misunderstood the question. I was thinking you
meant what if one of the arguments were not used, as in the example
below (see ?missing):
f<- function(d1, d2, d3)
{
vec <- c(missing(d1), missing(d2), missing(d3))
if(any(vec)) {
return(0)
}

hi all,
I have a data frame such as:
1 blue 0.3
1 NA0.4
1 red NA
2 blue NA
2 green NA
2 blue NA
3 red 0.5
3 blue NA
3 NA1.1
I wish to find the last non-missing value in every 3ple: ie I want a 3
by 3 data.frame such as:
1 red 0.4
2 blue NA
3 blue 1.1
I have written a little
I believe the usual practice in this case is simply to give default values
for arguments:
function(x, y, opt.arg1 = 0, opt.arg2 = sin(1),...)
If you haven't already done so, perusal of "An Introduction to R" --
especially the "Named Arguments and Defaults" -- would be appropriate.
Cheers,

Ok... then..
I didn't mean to start a flame war, so first off I apologize for firing
off my second comment.
I think a fair compromise is: I should have at least noted that I got
as far as finding dist() (and which.max()), thus showing "some" effort
on my part before posting my query.

Hello,
I am running into memory boundaries and would like to try to make use of the

Can anyone help with suggestions as to how this might work?
