The unique rows/values of x.
## create example data set d <- data.frame( x = rnorm(1000), y = seq.POSIXt(as.POSIXct("2018-01-01"), as.POSIXct("2018-12-31"), length.out = 10) ) ## sample to create version with duplicates dd <- d[c(1:1000, sample(1:1000, 500, replace = TRUE)), ] ## get only unique rows head(funique(dd)) ## check output identical(unique(dd), funique(dd))## create example data set d <- data.frame( x = rnorm(1000), y = seq.POSIXt(as.POSIXct("2018-01-01"), as.POSIXct("2018-12-31"), length.out = 10) ) ## sample to create version with duplicates dd <- d[c(1:1000, sample(1:1000, 500, replace = TRUE)), ] ## get only unique rows head(funique(dd)) ## check output identical(unique(dd), funique(dd))
