remove component from list or data frame
Sorry to ask such a simple question, but I can't find the answer after
extensive searching the docs and the web.
How do you remove a component from a list? For example say you have:
lst<-c(5,6,7,8,9)
How do you remove, for example, the third component in the list?
lst[[3]]]<-NULL generates an error: "Error: more elements supplied
than there are to replace"

search species with all absence in a presence-absence matrix
Dear list
I have a matrix composed of islandID as rows and speciesID as columns.
IslandID: Island A, B, C….O (15 islands in total)
SpeciesID: D0001, D0002, D0003….D0100 (100 species in total)
The cell of the matrix describes presence (1) or absence (0) of the species
in an island.
Now I would like to search the species with absence (0)
in all the islands (Island A to Island O.)

.Call question
Writing R Ext says to treat R objects that are arguments to .Call as
read only (i.e. don't modify).
I have a long list of lists that and I want to avoid the overhead of a
copy in my C code. I would just like to modify some of the elements
of list by replacing them with elements of exactly the same size/type.
below is an example of the essence of the problem. This seems to work.
