I hadn't seen 'comment' before, so don't take my suggestion as
authoritative. It looks useful, so I investigated a bit.
This technique seems to work and is (perhaps?) easier than names:

comment(x) - unlist(sapply(tlist, as.character))
or in one line
As I recall (my memory may be faulty), Tinn-R installation required admin

No time to really think about this, but:
a) to convert scattered point distributions to polygons you might look at
convex hulls; e.g. convhulln {geometry}
b) to identify islands some kind of cluster analysis
Hope that helps a little.

Hello,
how convert x in xarray (numbers)?
x
[1] 0 - 13
y
[1] 11 - 23
z
[1] 220 - 9
xarray
[1] 0 13
yarray
[1] 11 23
zarray
[1] 220 9
Thanks,

Although the indentation is just personal preference.
Just in case some of x are negative (the desired median still exists, as
long as the two middle values are non -ve), how about:
x - runif(20, -1, 100)
exp(median(log(pmax(0,x
It'll give -Inf if the two middle values are negative, when I guess we
should get NaN, but I can't see a 1-line way
or an odd number of negative numbers it becomes 0 or imaginary
(please do correct me if I'm wrong)?
sqrt(prod(c(2, 0, 54)))
sqrt(prod(c(-2, 2)))
Greg Snow, what is the scientific question? What is the model?

I don't think Ivan's solution meets the OP's needs.
I think you could do it using %in% and the approriate logical operations
e.g.
aDF - data.frame(id=c(1,2,2,2,3,3,4,4,4,5),
diagnosis=c(ah, ah, ihd, im, ah, stroke, ah, ihd,
angina, ihd))
aDF[with(aDF,(id %in% id[diagnosis==ah]) (id %in%
I did try it. It gave me
[[1]]
id diagnosis
1 1ah
5 3ah
7 4ah
8 4 ihd
10 5 ihd
[[2]]
id diagnosis
1 1ah
2 2ah
5 3ah
7 4ah
[[3]]
id diagnosis
3 2 ihd
8 4 ihd
10 5 ihd
Which isn't what
Just looking at the ambiguity in adding a year
dates - as.Date(c('2007-03-01','2008-02-29'))
tmp - as.POSIXlt(dates)
tmp$year - tmp$year+1
dates2 - as.Date(tmp)
dates2
[1] 2008-03-01 2009-03-01
dates2 - dates
Time differences in days

OK, someone point it out to me; my wife tells me I can't see what's in front

I read ?expand.grid carefully, went to ?combn and ?choose but still couldn't
see an easy way to get what the OP asked for. The neatest I can get (which
isn't very neat!) is:
myVec - c(1,2,3)
eg -
to a solution.
I used [, which I couldn't see suggested on ?expand.grid.
I thought I'd missed a neater solution in the help pages, and hoped someone
could point it out.

If you don't want the information as character, why are you printing it
rather than storing it in a matrix?
Why not something along the lines of this...
fr - function(x) { ## Rosenbrock Banana function
on.exit(aMatrix - rbind(aMatrix,(cbind(x1, x2, f
x1 - x[1]
x2 - x[2]

If you don't want the information as character, why are you printing it

Why not something along the lines
(list.files(path=.libPaths(),
full.names=TRUE), etc), pattern=^menus\\.txt$, full.names=TRUE)
a reasonable replacement for the Sys.glob() construction in Rcmdr? I don't
want to suggest to Prof. Fox an amendment which fixes my problem but
'breaks' it for others!

I think codetools could do this reasonably well with the walkCode function,
but I've never done it so I don't have sample code, and walkCode is mostly
an internal function.
There are a couple of approaches here:
Alternatively, with approx() use xout to specify which interpolated
values you want returned:
approx(dat, xout=dat$V1[is.na(dat$V2)])
