Examples

c(1:100) %ni% c(2, 3, 5, 10, 78:91)

#subset data to extract rows with matching values using "%in%"
subset(pdata, g %in% c("a", "e"))

#subset data to extract rows with non-matching values using "%ni%"
subset(pdata, g %ni% c("a", "e"))

#equivalent to subset function for tidyverse users
dplyr::filter(pdata, g %ni% c("a", "e"))
