Format confidence intervals

Creates 'APA'-formatted confidence intervals, either from an object for which a method exists, or from the arguments lb and ub. When argument x is a numeric vector, it is also possible to construct a confidence interval using the standard error (se) and a percentile interval (ci).

conf_int(x, digits = 2, se = NULL, lb = NULL, ub = NULL, ci = 95)

Arguments

x

Optional. An object for which a method exists.

digits

Integer. The number of digits to round the confidence boundaries to.

se

Optional, numeric. Standard error of the parameters.

lb

Optional, numeric. Lower boundary of confidence intervals.

ub

Optional, numeric. Upper boundary of confidence intervals.

ci

Optional, numeric. What percentage CI to use (only used when computing CI from a numeric vector x, and the standard error se, based on a normal distribution).

Value

A character vector of formatted confidence intervals.
