How to create lower dimensional matrix from higher dimensional array in R?

Question

Suppose I have an array such that: ``` temp<-array(0, dim=c(100,10,4)) ``` I can merge matrices 1 & 2 from the array into a single matrix using cbind: ``` temp.merge<-cbind(temp[,,1],temp[,,2]) ``` Is there a way to merge all n matrices (in this case 4) into a single one without having to write out the position of each one as above?

Accepted Answer

If you have the array set up right in memory, you can just reset the dimensions and it will work.

```
dim(temp) <- c(100, 40)
```
