Hi all Forgive me, I'm a total R newbie, and this seems to be a straightforward simple bootstrap problem, but after a whole day of trying to figure out how to do it I'm ready to give up. Part of the problem is that every example and every help page seems to be about doing something more far more complex.
I'm got a table with 40 columns and 750 rows. I sum all the values across the whole table (and subsets of the columns). I want to bootstrap to get the 95% confidence intervals for that sum value. result <- boot(table, <function>, 1000) boot.ci (result, bca) It seems to me that the 'function' is something to sum all the columns and rows of the table (or a subset should I desire). I've tried writing 'sum' for the function, but this gives me a huge figure which can't possibly be right.
