Subject: Using a list as multidimensional indexer
Hello list.
Another 'puzzle' for which I don't have a clean solution.
Say I have a multidimensional object, e.g.:
Mm<-matrix(1:6, nrow=2, dimnames=list(c("a","b"), c("g","h","i")))
And on the other hand I have a list
Ind<-list("b","g")
This holds, for each dimension, an indexer for that dimension.
Now I would like to get the element pointed at by the list.
The obvious solutions don't seem to work, and I can't seem to get do.call to
call the indexer ('[') on my multidimensional object.
Any suggestions?
Thanks in advance,
Nick Sabbe
