text_field and arrays
Hi,
I''m trying to do a bulk update on an array with the helper text_field.
I''m trying to create an inputfield for every object in the array, but
I''m not getting it right...
example:
class ClassA
@arrayB[]
end
HTML (code with error):
<% 0.upto(9) do |index| %>
<%= text_field ''ClassA'', ''arrayB[index]'' %>
non working alternative:
<%= text_field ''ClassA[arrayB][]'', ''index'' %>
Thanks in advance,
Bas

resampling for correlation and testing
...n B matrix.
Some example code:
A<-matrix(rnorm(100), ncol=10)
B<-matrix(rnorm(100), ncol=10)
rho.A<-cor(A)
{
idx<-sample(1:10, 10)
idx
# [1] 8 4 5 7 1 9 2 10 6 3
rho.B<-cor(B[,idx])
} ## repeat this x time (currently 500)
## in essence we then have the following :
rho.arrayB<-array(runif((10*10)*500), dim=c(10,10,500))
## Then test if rho.A[1,1] come from the distribution of rho.B[1,1]
pvalueMat[1,1]<-wilcox.test(rho.array[1,1,] , rho.A[1,1])$p.value
However, my array size would be 2300 x 2300 x 500 which R won't let me even make as an empty structure. Any...
