For example, > x <- 1:8 > plot(1:10, 1:10) > text(5, 5, expression(sum(x[i], i == 1, length(x))) # would like "8" # substituted for length(x) here Is there a way to replace length(x) with the returned value of the function? Thanks for any advice, Matt ---------------------------------------------------------------------------- Matthew R.
