Benchmark

Hi,
No issue but I wanted to share with you the function funique in package kit v0.0.4.
Please see benchmark below.
Thank you

## set seed
set.seed(20180812)

## generate data
d <- data.frame(
  x = rnorm(1000),
  y = seq.POSIXt(as.POSIXct("2018-01-01"),
                 as.POSIXct("2018-12-31"), length.out = 10))

## create data frame with duplicate rows
d <- d[c(1:1000, sample(1:1000, 500, replace = TRUE)), ]
row.names(d) <- NULL

## check the output against base::unique
identical(unique(d), funique::funique(d))
identical(unique(d), kit::funique(d))

## bench mark
microbenchmark::microbenchmark(
  base=unique(d),
  funique=funique::funique(d),
  kit=kit::funique(d),

  unit = "relative"
