Description Usage Arguments See Also Examples

These operators introduce improved NA handling, reliable floating point tests, and intervals. Specifically:

Equality that handles missing values

Floating point equality, an important bit of functionality missing in base R (

`%~=%`

)Strict (value and type) equality, for those familiar with Javascript's

`===`

Greater/less than or equal to with missing value equality

Greater/less than or equal to with floating point and missing equality

Between (ends excluded)

Between (ends included)

1 2 3 4 5 6 7 8 9 10 11 | ```
x %==% y
x %===% y
x %>=% y
x %<=% y
x %><% y
x %>=<% y
``` |

`x` |
a vector |

`y` |
a vector |

Other comparisons: `%~=%`

## Greater/Less than | Equal
c(1, NA, 3, 4) == c(1, NA, 4, 3)
# TRUE NA FALSE FALSE
c(1, NA, 3, 4) %==% c(1, NA, 4, 3)
# TRUE TRUE FALSE FALSE
c(1, NA, 3, 4) %>=% c(1, NA, 4, 3)
# TRUE TRUE FALSE TRUE
c(1, NA, 3, 4) %<=% c(1, NA, 4, 3)
# TRUE TRUE TRUE FALSE
# Strict equality - a la javascript's ===
# Only tru if the class and value of x and y are the same
x <- int(2)
y <- 2
x == y # TRUE
x %===% y # FALSE
x %===% int(y) # TRUE
# NOTE parentheses surrounding expression before this operator are necessary
# Without parentheses it would be interpreted as .1 + .1 + (.1 %~=% .3)

2 %><% c(1, 3)
# TRUE

# FALSE
