These are the results of calling benchmark64()

Usage

data(benchmark64.data)

Format

The format is:

num [1:16, 1:6] 2.55e-05 2.37 2.39 1.28 1.39 ...
- attr(*, "dimnames")=List of 2
..$ : chr [1:16] "cache" "match(s,b)" "s %in% b" "match(b,s)" ...
..$ : chr [1:6] "32-bit" "64-bit" "hashcache" "sortordercache" ...

Examples
