Extract confidence intervals, test statistics or p-values from an
htest
object.
# S3 method for htest

# S3 method for htest
pval(x, digits = 4, verbose = FALSE, ...)
stat(x, ...)
# S3 method for htest
stat(x, ...)
a fitted model object or an htest object.
a specification of which parameters are to be given confidence intervals, either a vector of numbers or a vector of names. If missing, all parameters are considered.
the confidence level required.
Additional arguments.
