Is it?
Description
A set of functions that check whether an object has the desired characteristics.
Usage
is_whole(x, tol = .Machine$double.eps^0.5)
is_atvec(x)
is_numatvec(x)
is_nummat(x)
is_numarray(x)
is_symmetric(x)
is_pd(x)
is_pos(x)
is_integer(x)
is_natural(x)
Arguments
x |
numeric vector or matrix. |
tol |
numeric. The tolerance for a numeric to be considered a whole number. |
Value
logical. TRUE or FALSE, depending on whether the object satisfies the checks that define the characteristic.
Functions

is_pd()
: Is the object a positive definite matrix? -
is_pos()
: Are all the elements finite and positive? -
is_integer()
: Is the object an integer in the mathematical sense? -
