A count is defined as non-negative integerish value.

checkCount(
x,
na.ok = FALSE,
positive = FALSE,
tol = sqrt(.Machine$double.eps), null.ok = FALSE ) check_count( x, na.ok = FALSE, positive = FALSE, tol = sqrt(.Machine$double.eps),
null.ok = FALSE
)

assertCount(
x,
na.ok = FALSE,
positive = FALSE,
tol = sqrt(.Machine$double.eps), null.ok = FALSE, coerce = FALSE, .var.name = vname(x), add = NULL ) assert_count( x, na.ok = FALSE, positive = FALSE, tol = sqrt(.Machine$double.eps),
null.ok = FALSE,
coerce = FALSE,
.var.name = vname(x),
)

testCount(
x,
na.ok = FALSE,
positive = FALSE,
tol = sqrt(.Machine$double.eps), null.ok = FALSE ) test_count( x, na.ok = FALSE, positive = FALSE, tol = sqrt(.Machine$double.eps),
null.ok = FALSE
)

expect_count(
x,
na.ok = FALSE,
positive = FALSE,
tol = sqrt(.Machine$double.eps), null.ok = FALSE, info = NULL, label = vname(x) ) ## Arguments x [any] Object to check. na.ok [logical(1)] Are missing values allowed? Default is FALSE. positive [logical(1)] Must x be positive (>= 1)? Default is FALSE, allowing 0. tol [double(1)] Numerical tolerance used to check whether a double or complex can be converted. Default is sqrt(.Machine$double.eps).

null.ok

[logical(1)]
If set to TRUE, x may also be NULL. In this case only a type check of x is performed, all additional checks are disabled.

coerce

[logical(1)]
If TRUE, the input x is returned as integer after an successful assertion.

.var.name

[character(1)]
Name of the checked object to print in assertions. Defaults to the heuristic implemented in vname.

[AssertCollection]
Collection to store assertion messages. See AssertCollection.

info

[character(1)]
Extra information to be included in the message for the testthat reporter. See expect_that.

label

[character(1)]
Name of the checked object to print in messages. Defaults to the heuristic implemented in vname.

## Value

Depending on the function prefix: If the check is successful, the functions

assertCount/assert_count return

x invisibly, whereas

checkCount/check_count and

testCount/test_count return

TRUE. If the check is not successful,

assertCount/assert_count

throws an error message,

testCount/test_count

returns FALSE, and checkCount/check_count

return a string with the error message. The function expect_count always returns an

expectation.

## Details

This function does not distinguish between NA, NA_integer_, NA_real_, NA_complex_ NA_character_ and NaN.

## Note

To perform an assertion and then convert to integer, use asCount. assertCount will not convert numerics to integer.

Other scalars: checkFlag(), checkInt(), checkNumber(), checkScalarNA(), checkScalar(), checkString()
