confint.numeric: Confidence interval methods for output of resampling

Description

Methods for confint to compute confidence intervals on numerical vectors and numerical components of data frames.

Usage

## S3 method for class 'numeric':
confint(object, parm, level = 0.95,
    ..., method = c("stderr", "quantile"), margin = FALSE)
  ## S3 method for class 'data.frame':
confint(object, parm, level = 0.95,
    ..., method = c("stderr", "quantile"), margin = FALSE)

Arguments

object

The data frame or numerical vector.

parm

not used -- for compatibility with other confint methods

level

confidence level (default 0.95)

...

additional arguments (currently ignored)

method

either "stderr" (default) or "quantile"

margin

if true, report intervals as a center and margin of error.

Value

• When applied to a data frame, returns a data frame giving the confidence interval for each variable in the data frame. When applied to a numerical vector, returns a vector.

Examples

s <- do(500)*mean( age ~ sex, data=resample(HELPrct) )
confint(s)
confint(s, method="quantile")
confint(s, margin=TRUE)
confint(s, margin=TRUE, level=0.99 )
s2 <- do(500)*mean( resample(1:10) )
confint(s2)
