confint: Confidence Intervals for Numeric Vectors

In miscset: Miscellaneous Tools Set

Description

Calculate confidence intervals for values of a numeric vector.

Usage

## S3 method for class 'numeric'
confint(object, parm = qnorm, level = 0.95, ...,
  na.rm = TRUE, ret.attr = TRUE)

Arguments

object	A numeric vector.
parm	Function for quantile calculation. e.g. qnorm, qt
level	Size of confidence (0 < size < 1).
...	Unused.
na.rm	Logical, remove missing values for sd and mean.
ret.attr	Logical, to include the mean value and function arguments as attributes of the returned object.

Value

Returns a numeric vector with the lower and upper range of the confidence interval.
