Tidy a logitr class object
# S3 method for logitr
tidy(x, conf.int = FALSE, conf.level = 0.95, ...)is an object of class logitr.
Logical indicating whether or not to include a confidence interval in the tidied output. Defaults to FALSE.
The confidence level to use for the confidence interval if conf.int = TRUE. Must be strictly greater than 0 and less than 1. Defaults to 0.95, which corresponds to a 95 percent confidence interval.
Unused, included for generic consistency only.
