abind works well for this example.
a1 <- array(1:18, dim=c(3,3,2))
a2 <- array(101:150, dim=c(5,5,2))
a1b <- abind(a1, array(400, dim=c(2,3,2)), along=1)
a1c <- abind(a1b, array(500, dim=c(5,2,2)), along=2)
dim(a1c)
a1
a2
a1c

Hi,
I have two 3 D arrays. Both are of this form
array_1<- array[n,n,k]
array_2<-array[m,m,k]
Lets say n=83 and m=80
Since n>m. I would like to add rows and columns to array_2 to make them
equal. I want to keep the size of the third dimension fixed i.e.. k.
i.e.
if (nrow(array_1)>nrow(array_2))
Thank you Joshua!! StatTemps[c(1:7, 22:34), ] that's what i needed! I
needed different ranges of rows but it is exactly what i was looking for.
Thanks so much!! R can be kind of fun! hehe

Hi Brian,
I believe there was some miscommunication earlier due to R's array
class for objects and the colloquial usage of array (the idea that
'array' is used colloquially is a bit odd, but I digress). In any
case, here are some steps I take (certainly not the only ones) when
exploring a new dat
if you can load the PASWR package and pull up StatTemps you will see what I
am talking about. Otherwise I fear that my question will just be confusing.

Instead of:
7:11&23:34
I think you mean:
c(7:11, 23:34)
Using '&' for concatenation
is not an unreasonable idea,
but it is decidedly not what
R does.
It would be instructive to do:
7:11 & 23:34
at the R prompt to see what you
get.

Hi B,
What you need to do is pass a vector with the indices you want to
extract. So, you have 1:7 (which expands to 1, 2, 3, ... 7) and 12:34
(which again expands). How would you combine two sets of numbers?
c(), the combine or concatenate function. Putting this in action:
mya <- array(1:510,
Hi! I am learning R and have a question that is probably fairly simple for
those of you much more learned than I.
I am messing with Arrays and am doing some simple stuff to get the hang of
them. I will have a seperate array already pulled up and it will have
columns and rows. I figured out th
