selecting vector elements using matrices and combining the results
I've been scratching my head over this one for too long. I'm hoping
someone out there can solve this riddle.
I have two vectors of characters, v1 and v2, both of length L, and two
matrices of logicals, m1 and m2, both of dimension N*L. The first matrix
of logicals corresponds to the first vector of characters, and the second
to the second.
The matrices are telling me which of the

inset one map on top of another map
I want to overlay a small inset map on top of another map, but I can't
figure out how to do it.
For example, here are two different maps:
# map 1 - Ohio
map("state", region= "ohio")
# map 2 - US with Ohio darkened
map("state")
map("state", region="ohio", fill=T, add=T)
I would like to add map 2 as a small inset in the corner of map 1.

efficient coding with foreach and bigmemory
I recently learned about the bigmemory and foreach packages and am trying
to use them to help me create a very large matrix. Without those
packages, I can create the type of matrix that I want with 10 columns and
5e6 rows. I would like to be able to scale up to 5e9 rows, or more, if
possible.
I have created a simplified example of what I'm trying to do, below. The

Are loops handled differently in newer versions of R?
Hi gang,
I'm perplexed- I have some code that uses for() loops that works fine in
R version 2.8 on my mac, worked fine in version 2.8 on my old windows
machine, but doesn't work in version 2.10 on windows.
The loop implements a function over a data frame (code is included below).
In Mac (running version 2.8), the results of the loop are what I expect:

using "na.locf" from package zoo to fill NA gaps
Hi everybody,
I have a small question about the function "na.locf" from the package "zoo".
I saw in the help that this function is able to fill NA gaps with the last
value before the NA gap (or with the next value).
But it is possible to fill my NA gaps according to the last AND the next
value at the same time?
Actually, I want R to fill my gaps with the method of

Fwd: offset en bucle
Amigos de la erre.
He creado mi primer bucle con for para entrenar unos modelos con GAM. La
respuesta es quasipoisson porque estoy trabajando con densidades de peces.
Sin embargo, tengo un problema, no se muy bien como añadir el offset a la
formula siguiente cuando creo el bucle.
GAM.A1 <-gam ((DYO)~s(DMA,k=4)+ s(WOD,k=4)+s(CIN,k=4)+s(DRA,k=4)+s(DBR,k=4)

ogg file header?

new ogg file will not play. i think the problem is that i do not
understand what needs to be changed in the 1st header. right now i am

last observation carried forward +1
Hi R-helpers
I'm looking for a vectorised function which does missing value replacement
as in last observation carried forward in the zoo package but instead of a
locf, I would like the locf function to add +1 to each time a missing value
occurred. See below for an example.
> require(zoo)
> x <- 5:15
> x[4:7] <- NA
> coredata(na.locf(zoo(x)))

data.frame with NA
I have this little data.frame
http://dl.dropbox.com/u/102669/nanotna.rdata
Two column contains NA, so the best thing to do is use na.locf function (with
fromLast = T)
But locf function doesn't work because NA in my data.frame are not recognized as
real NA.
Is there a way to substitute fake NA with real NA? In this case na.locf function
should work
Thank you
