Print methods for hyper2 and hyper3 objects

# S3 method for class 'hyper2'
print(x, ...)
# S3 method for class 'hyper3'
print(x, ...)

Arguments

x: An object of class hyper2 or hyper3
...: Further arguments, currently ignored

Value

Returns the hyper2 or hyper3 object it was sent, invisibly. Function pnv() converts a named vector to a character string that is used in the hyper3 print method.

Details

Used mainly for their side-effect of printing the log-likelihood function. In the print method, a natural logarithm is indicated with “log()”—not “ln()”—consistent with R builtin terminology base::log().

The hyper2 print method is sensitive to option give_warning_on_nonzero_power_sum. If TRUE, a warning is issued if the powers have nonzero sum. This is usually what you want because observations are typically multinomial; a warning indicates nonzero sum of powers, which should prompt us to check the coding. Vignette zeropower gives a discussion of this issue.
