Print Method for bbssr_ppowerbssr Objects — print.bbssr

Prints the power and the expected final number of pairs of a matched-pairs design with blinded sample size re-estimation.

Usage

# S3 method for class 'bbssr_ppowerbssr'
print(x, digits = 4, ...)

Arguments

x: An object of class bbssr_ppowerbssr returned by PairedPowerBSSR
digits: Number of decimal places. Default is 4
...: Further arguments, ignored

Value

x, invisibly

Details

An object whose attributes were removed, for example by selecting some of its columns, is printed as a data frame.

Examples

res <- PairedPowerBSSR(psi = c(0.2, 0.3), Delta.T = 0.15, Delta.A = 0.15, N = 72,
                       n.interim = 30, alpha = 0.05, tar.power = 0.8,
                       Test = 'McNemar', alternative = 'two.sided',
                       ss.method = 'standard')
print(res)
