[R] partial match gotcha

[Robin Hankin]

Hi

The following gotcha took me a long time to catch:

f <- function(x, main0="red", ...){
   par(col.axis=main0)
   plot(x,...)
}

f(1:10,main="title here")
f(1:10,main="title here",main0="blue")


I can't quite succinctly summarize why the second case works but the  
first one
doesn't.
