Description

Robust Descriptives

Usage

rdesc(
  data,
  vars,
  splitBy = NULL,
  mean = TRUE,
  trim = TRUE,
  tr = 0.2,
  win = FALSE,
  wl = 0.2,
  mest = FALSE,
  bend = 1.28,
  med = FALSE
)

Arguments

data	the data as a data frame
vars	a vector of strings naming the variables in data of interest
splitBy	a string naming the variable in data to split the data by
mean	TRUE (default) or FALSE, provide a 'normal' arithmetic mean
trim	TRUE (default) or FALSE, provide a trimmed mean
tr	a number between 0 and 0.5 (default: 0.2); the proportion of measurements to trim from each end when producing trimmed means
win	TRUE or FALSE (default), provide a 'Winsorized' mean
wl	a number between 0 and 0.5 (default: 0.2); the level of 'winsorizing' when producing winsorized means
mest	TRUE or FALSE (default), provide an 'M-estimated' value
bend	a number (default: 1.28), the bending constant to use when using M-estimators
med	TRUE or FALSE (default), provide medians

Value

A results object containing:

results$table					the table of descriptives

Tables can be converted to data frames with asDF or as.data.frame. For example:

results$table$asDF

as.data.frame(results$table)

Examples

data('eurosoccer', package='WRS2')

SpainGermany <- subset(eurosoccer, eurosoccer$League == 'Spain' | eurosoccer$League == 'Germany')
SpainGermany <- droplevels(SpainGermany)

walrus::rdesc(
    data = SpainGermany,
    vars = "GoalsGame",
    splitBy = "League",
    med = TRUE)
