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_overlapping() checks if two data ranges overlap at all.
is_constant(x, tolerance = .Machine$double.eps^0.5, na.rm = TRUE)is_increasing(x, na.rm = TRUE)
is_decreasing(x, na.rm = TRUE)
A numeric object to be tested.
A numeric scalar giving the tolerance to check within.
A logical scalar: should missing values (including NaN)
be omitted?
A logical scalar.
