| minmax {magic} | R Documentation |
Returns TRUE if and only if all elements of a vector are identical.
minmax(x, tol=1e-6)
x |
Vector to be tested |
tol |
Relative tolerance allowed |
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
