is_numeric_linter {lintr} | R Documentation |
Redirect is.numeric(x) || is.integer(x)
to just use is.numeric(x)
Description
is.numeric()
returns TRUE
when typeof(x)
is double
or integer
–
testing is.numeric(x) || is.integer(x)
is thus redundant.
Usage
is_numeric_linter()
Details
NB: This linter plays well with class_equals_linter()
, which can help
avoid further is.numeric()
equivalents like
any(class(x) == c("numeric", "integer"))
.

Examples
# will produce lints
lint(
text = "is.numeric(y) || is.integer(y)",
linters = is_numeric_linter()
)
lint(
text = 'class(z) %in% c("numeric", "integer")',
linters = is_numeric_linter()
)
# okay
lint(
text = "is.numeric(y) || is.factor(y)",
linters = is_numeric_linter()
)
lint(
text = 'class(z) %in% c("numeric", "integer", "factor")',
linters = is_numeric_linter()
)
