Vacuum is an implementation in R of three procedures developed byJohn Tukey: FUNOP (FUll NOrmal Plot), FUNOR-FUNOM(FUll NOrmal Rejection-FUll NOrmal Modification), and vacuum cleaner.Combined, they provide a way to identify, treat, and analyze outliersin two-way (i.e., contingency) tables, as described in hislandmark paper "The Future of Data Analysis", Tukey, John W. (1962)https://www.jstor.org/stable/2237638.

You can install the released version of vacuum fromCRAN with:

install.packages("vacuum")

You can install the development version, which currently contains only documentation changes, fromGitHub with:

# install.packages("devtools")devtools::install_github("sielinski/vacuum")

funop identifies outliers in a numeric vector:

library(vacuum)# example datadat<-  c(14,-104,-97,-59,-161,93,454,-341,54,137,473,45,193,22)# outliers flagged as TRUE in the "special" columnfunop(dat)
