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)
A logical scalar.
