Compare-methods {frab}

Comparision methods

Description

Methods for comparison (greater than, etc) in the frab package.

Functions frab_gt_num() etc follow a consistent naming convention; the mnemonic is the old Fortran .GT. scheme [for “greater than”].

Function frab_eq() is an odd-ball, formally documented at Arith.Rd. It is slightly different from the other comparisons: it calls low-level helper function c_frab_eq(), which calls its C namesake which is written for speed (specifically, returning FALSE as soon as it spots a difference between its two arguments). Note that if any value is NA, frab_eq() will return FALSE.

Usage

frab_eq(e1,e2)
frab_compare_frab(e1,e2)
frab_eq_num(e1,e2)
frab_ne_num(e1,e2)
frab_gt_num(e1,e2)
frab_ge_num(e1,e2)
frab_lt_num(e1,e2)
frab_le_num(e1,e2)
frab_compare_numeric(e1,e2)
num_eq_frab(e1,e2)
num_ne_frab(e1,e2)
num_gt_frab(e1,e2)
num_ge_frab(e1,e2)
num_lt_frab(e1,e2)
num_le_frab(e1,e2)
numeric_compare_frab(e1,e2)
