"r" is probably matching "recursive", but what about "u"? ("unlist"??)
Aha! It's matching use.names (one of the arguments of unlist())
c(u=0,x=1,y=2)
[1] 1 2
c(u=10,x=1,y=2)
x y 1 2 Isn't it a bit dangerous to allow partial matching of arguments (especially undocumented arguments)? NB It doesn't consistently match the arguments either:
c(r=1,u=2)
u 2
c(u=2,r=1)
