Well, this problem also happens in the correct context for "=" (named
function arguments.)

  matrix(data=c(1, 2, 3,
           4, 5, 6,
           7, 8, 9),
         byrow=TRUE,
         nrow=3)

should rather be indented as:

  matrix(data=c(1, 2, 3,
                4, 5, 6,
                7, 8, 9),
         byrow=TRUE,
         nrow=3)
