Complicated analysis for huge databases
The loop :
AllMAFs <- list()
for (i in length(SeparatedGroupsofmealsCombs) {
AllMAFs[[i]] <- apply( SeparatedGroupsofmealsCombs[[i]], 2, function(x)maf( tabulate( x+1) ))
}
gives these errors (I tried this many times and I'm sure I copied it entirely) :-
Error in apply(SeparatedGroupsofmealsCombs[[i]...

Something like the following?
AllMAFs <- list()
for (i in length(SeparatedGroupsofmealsCombs) {
AllMAFs[[i]] <- apply(SeparatedGroupsofmealsCombs[[i]], 2, function(x)maf(tabulate(x+1)))
}
(untested, of course)
Also the solution is a bit generic since I don't know what the output of maf() looks like in your case, and I do...

The correct code is:
for (i in 1:length(SeparatedGroupsofmealsCombs)) { ...
I had mentioned that this is untested, but the error is so obvious ...

Thanks Boris , this was very helpful but I'm struggling with the last part.
1) I combined the first 2 columns :-
library(tidyr)
SingleMealsCode <-unite(MyData, MealsCombinations, c(MealA, MealB), remove=FALSE)
SingleMealsCode <- SingleMealsCode[,-2]
2) I separated this dataframe into different dataframes based on "MealsCombination"
column so R will recognize each meal

Combine columns 1 and 2 into a column with a single ID like "33.55", "44.66" and use split() on these IDs to break up your dataset. Iterate over the list of data frames split() returns.
