Dependency Condition

Condition object, to specify the condition in a dependency.

condition_test(cond, x)

condition_as_string(cond, lhs_chr = "x")

Condition(rhs, condition_format_string)

`cond`	(`Condition`) `Condition` to use
`x`	(`any`) Value to test
`lhs_chr`	(`character(1)`) Symbolic representation to use for `⁠<lhs>⁠` in the returned string.
`rhs`	(`any`) Right-hand-side of the condition.
`condition_format_string`	(`character(1)`) Format-string for representing the condition when pretty-printing in `condition_as_string()`. Should contain two `⁠%s⁠`, as it is used in an `sprintf()`-call with two further string values.

condition_test(): Used internally. Tests whether a value satisfies a given condition. Vectorizes when x is atomic.
condition_as_string(): Used internally. Returns a string that represents the condition for pretty printing, in the form "<lhs> <relation> <rhs>", e.g. "x == 3" or "param %in% {1, 2, 10}".
