Check numeric objects:

  • is_constant() checks for equality among all elements of a vector.

  • is_increasing() and is_decreasing() check if a sequence of numbers is monotonically increasing or decreasing, respectively.

is_constant(x, tolerance = .Machine$double.eps^0.5, na.rm = FALSE)

is_increasing(x, na.rm = FALSE)

is_decreasing(x, na.rm = FALSE)

is_greater(x, y, strict = FALSE, na.rm = FALSE)

is_lower(x, y, strict = FALSE, na.rm = FALSE)

Arguments

x, y

A numeric object to be tested.

tolerance

A numeric scalar giving the tolerance to check within.

na.rm

A logical scalar: should missing values (including NaN) be omitted?

strict

A logical scalar: should strict inequality be used?

Value

A logical scalar.
