Hi! I've tried on SO, but without success. Maybe you will be able to
help. I have the following array (I use 3-dimensional in this example for
simplicity, but it can be 3+ dims - 10,11 or more): a <- c('a1',
'a2', 'a3') b <- c('bb', 'bbb') c <-
c('C', 'CC', 'CCC') dimNa <- list('a' = a,
'b' = b, 'c' = c) outputArray <- array(NA,
unname(sapply(dimNa, function(x) length(x), simplify = T)),
unname(dimNa)) I can subset it using name from one dimension manually, like:
> outputArray[,'bb',] C CC CCC a1 NA NA NA a2 NA NA NA a3
NA NA NA or > outputArray[,,'CCC'] bb bbb a1 NA NA a2 NA
NA a3 NA NA I would like to write a function which subsets particular
named element from one dimension (I mean I don't expect one dimension as a
result by slicing using one named element, if that makes sense). Something like
myfunc <- function(inputArray, namedElement) thus I can call it (using
above example): myfunc(outputArray, 'bb') or myfunc(outputArray,
'CCC') to get identical as above results. I know how to deal with
finding to which dimension "namedElement" belongs (in my case all names
are unique). The question is how to subset it from the array? One idea is to
construct what is inside [ ] (in example: ,'bb', or ,,'CCC').
I've tried something like this: inputDims <-
",,'CCC'" outputArray[parse(text=inputDi But this
doesn't work. Maybe different approach should be used... Any ideas are
welcome:)! Cheers!
