minmax {magic} | R Documentation |
are all elements of a vector identical?
Description
Returns TRUE
if and only if all elements of a vector are identical.
Usage
minmax(x, tol=1e-6)
Arguments
x |
Vector to be tested |
tol |
Relative tolerance allowed |
Details
If x
is an integer, exact equality is required. If real or
complex, a relative tolerance of tol
is required. Note that
functions such as is.magic()
and is.semimagichypercube()
use the default value for tol
. To change this,
define a new Boolean function that tests the sum to the required
tolerance, and set boolean
to TRUE
