Multiple lapply get-around
I am faced with a situation wherein I have to use multiple lapply's. The
pseudo-code could be approximated to something as below:
For each X from i=1 to n
For each Y based on j=1 to m
For each F from 1 to f
Do some calculation based on Fij
Store Xi,Yj = Fij
End For F
End for Y
End for X
Is there anyway to optimize the processing logic further? I *guess*
using the multiple lapply already optimizes the logic a little bit but
is there anything else that could be done (apart from the obvious
solution of writing a c-code)?
TIA

"Matrix' with Functions
Dear R members,
I have a quite large of function that are named like that
f11,f12,...f15
f21,f22,...f25
..
f51,f52,...f52
These are static (hard-coded) functions that the only common they have is that they take the same number and type of input fij(a,b,c,d). As you might understand this is really close to the notion of matrix only that my 'matrix' contains functions. It would be great if I can address all these function using a numbering-scheme like F(i,j) where for example
F(1,1) will return the f11(a,b,c,d,).
I am sure that this mi...
