R-beta: Including an evaluated function in text expression
R-users, I would like to take advantage of R's mathematical typesetting capabilities in the graphical environment using text(..., expression(...)), however, I can't figure out how to include in the expression some evaluated function. 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.
