Block usage like x %in% "a"
Description
vector %in% set
is appropriate for matching a vector to a set, but if
that set has size 1, ==
is more appropriate.
Usage
scalar_in_linter(in_operators = NULL)
Arguments
in_operators |
Character vector of additional infix operators that behave like the |
Details
scalar %in% vector
is OK, because the alternative (any(vector == scalar)
)
is more circuitous & potentially less clear.

Examples
# will produce lints
lint(
text = "x %in% 1L",
linters = scalar_in_linter()
)
lint(
text = "x %chin% 'a'",
linters = scalar_in_linter(in_operators = "%chin%")
)
# okay
lint(
text = "x %in% 1:10",
linters = scalar_in_linter()
)
