When looking for functions whose exact name is unknown

# Functions related to “shrinkage” methods
help.search(“shrinkage”)

Package sos does a great job in finding functions

install.packages(“sos”)
library(sos)
shrinkageResults <- findFn("shrinkage", maxPages = 1)
shrinkageResults
# This opens a webpage in your browser with the results

The table in the webpage created above have sortable columns.

# Sort on creation data of resultant packages
summaryObj <- summary(shrinkageResults)
pkgTable <- summaryObj$PackageSummary
pkgTable <- pkgTable[order(pkgTable$Date,decreasing=T),]
