nonUniq: nonUniq: Find Replicated Elements In A Vector

In mwrowe/microRutils: Mike Rowe's Miscellaneous R Utility Functions

Description

nonUniq(x) returns items in x that occur more than once (indices or values)

Usage

nonUniq(x, value = F, na.rm = T)

Arguments

x	vector or matrix. Missing values are ignored.
value	logical; if TRUE, return the unique elements in x that occur more than once. If FALSE (default), return their indices.
na.rm	logical; if TRUE, ignore missing values (NA's)

Value

If value==F, an integer vector with positions (indices) of non-unique elements of x; otherwise, a vector with the unique elements of x that occur more than once. Thus: all(nonUniq(x, value=T)==unique(x[nonUniq(x)])) is TRUE
