Body
I've got a multidimensional array with 13,057 8X11 matrices inside it. <pre><code>dim(results) [1] 13057 8 11 </code></pre> Every time I to index a particular matrix, the values inside the matrix change. For example, say I do: <pre><code>head(results) [1] 0.2789366 0.1555067 0.3026808 0.1644631 0.2325074 0.3162973 </code></pre> but when I do <pre><code>results[1,,] [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [1,] 0.2789366 0.2789366 0.2789366 0.2789366 0.2789366 0.2789366 0.2789366 0.2789366 0.2789366 [2,] 0.1191516 0.1191516 0.1191516 0.1191516 0.1191516 0.1191516 0.1191516 0.1191516 0.1191516 [3,] 0.1805271 0.1805271 0.1805271 0.1805271 0.1805271 0.1805271 0.1805271 0.1805271 0.1805271 [4,] 0.1846702 0.1846702 0.1846702 0.1846702 0.1846702 0.1846702 0.1846702 0.1846702 0.1846702 [5,] 0.4004454 0.4004454 0.4004454 0.4004454 0.4004454 0.4004454 0.4004454 0.4004454 0.4004454 [6,] 0.1336974 0.1336974 0.1336974 0.1336974 0.1336974 0.1336974 0.1336974 0.1336974 0.1336974 [7,] 0.2155045 0.2155045 0.2155045 0.2155045 0.2155045 0.2155045 0.2155045 0.2155045 0.2155045 [8,] 0.5307715 0.5307715 0.5307715 0.5307715 0.5307715 0.5307715 0.5307715 0.5307715 0.5307715 </code></pre> Why are my all of my rows having the same value? This is NOT what the initial value of this matrix was before I put it in the multidimensional array nor is it the value I get when I print all of the matrices in the console. This is my code: <pre><code>range01 <- function(x){(x-min(x))/(max(x)-min(x))} results = array(0,dim=c(13057,8,11)) for( i in 1:13057) { ap <- as.numeric(unlist(ap.dv[i,1:11])) dv <- as.numeric(unlist(ap.dv[i,12:19])) m <- outer(ap, dv, FUN="*") m[is.na(m)] <- 0 m <- range01(m) results[] <- m } </code></pre> thanks.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
