[R-lang] apply through a list

[Michael Cysouw]

a general question, not specific to linguistics...

I have a (large) set of same-size matrices M1,M2,M3,... which I  
stored in a list. How do I apply a function over the same position of  
all matrices? For example, take the sum M1+M2+M3+...

I have not found any "apply" like variant that would do the trick.  
Any suggestions?

best
michael
