The {clock} #rstats📦 aims to add "safety" such as user control over ambiguous date calcs (what's 2022-01-31 + 1 month?) and new functions like year_quarter_day. But it won't replace lubridate

And a little something extra special for the advanced `case_when()` users out there

library(dplyr)

df <- tibble(x = c(1, 3, 0, 5, 0, 7))

df %>%
mutate(
case_when(
x == 0 ~ NA,
x <= 2 ~ tibble(type = "low", id = 0),
x <= 4 ~ tibble(type = "medium", id = 1),
.default = tibble(type = "high", id = 2)
)
)
#> # A tibble: 6 × 3
#> x type id
#> <dbl> <chr> <dbl>
#> 1 1 low 0
#> 2 3 medium 1
#> 3 0 <NA> NA

Two exciting new improvements coming to `case_when()` for those who can spot them 😉

x <- c(1, 3, 0, 5, 0, 7)

dplyr::case_when(
x == 0 ~ NA,
x <= 2 ~ "low",
x <= 4 ~ "medium",
.default = "high"
)
#> [1] "low" "medium" NA "high" NA "high"

Time flies. Today, it's seven years since {future} was first released on CRAN. The uptake has been greater than I could ever imagine. I've got to interact with our awesome #RStats community more than ever before - makes it so much more fun 🙏 futureverse.org #parallel

A line graph with 'Date' (2015-2022) on the horizontal axis and 'Number of reverse dependencies on CRAN' on the vertical axis. Rapidly growing curves for three packages, 'future', 'future.apply', and 'furrr', are shown with 'future' increasing the fastest.

A line graph with 'Date' on the horizontal axis and 'Download rates on CRAN (four-week averages)' on the vertical axis. The dates goes from mid 2015 to mid of 2022 and the ranks for 0 to 20%. Lines for package 'foreach', 'future', 'future.apply', and 'furrr' are displayed in different colors. The foreach curve is the highest but decreases slowly, whereas the other three are rapidly increasing toward the level of foreach.
