mosaic (version 0.8-1)

mean: Aggregating functions

Description

The mosaic package makes several summary statistic functions (like mean and sd) formula aware.

Usage

mean(x, ..., data, ..fun.. = base::mean)
  median(x, ..., data, ..fun.. = stats::median)
  range(x, ..., data, ..fun.. = base::range)
  sd(x, ..., data, ..fun.. = stats::sd)
  max(x, ..., data, ..fun.. = base::max)
  min(x, ..., data, ..fun.. = base::min)
  sum(x, ..., data, ..fun.. = base::sum)
  IQR(x, ..., data, ..fun.. = stats::IQR)
  fivenum(x, ..., data, ..fun.. = stats::fivenum)
  iqr(x, ..., data, ..fun.. = stats::IQR)
  prod(x, ..., data, ..fun.. = base::prod)
  sum(x, ..., data, ..fun.. = base::sum)
  favstats(x, ..., data, ..fun.. = fav_stats)
  var(x, ..., data, ..fun.. = stats::var)
  cor(x, y = NULL, ..., data = parent.frame())
  cov(x, y = NULL, ..., data = parent.frame())

Arguments

x

an object, often a formula

y

an object, often a numeric vector

..fun..

the underlyin function used in the computation

data

a data frame in which to evaluate formulas (or bare names)
