About the tidyverse

The tidyverse is an opinionated collection of R packages designed for data science.

See all the packages in the tidyverse:

tidyverse::tidyverse_packages(include_self = TRUE)

 [1] "broom"         "conflicted"    "cli"           "dbplyr"       
 [5] "dplyr"         "dtplyr"        "forcats"       "ggplot2"      
 [9] "googledrive"   "googlesheets4" "haven"         "hms"          
[13] "httr"          "jsonlite"      "lubridate"     "magrittr"     
[17] "modelr"        "pillar"        "purrr"         "ragg"         
[21] "readr"         "readxl"        "reprex"        "rlang"        
[25] "rstudioapi"    "rvest"         "stringr"       "tibble"       
[29] "tidyr"         "xml2"          "tidyverse"

pak

Install the newest versions of packages using pak:

pak::pak(c("tidyverse", "dplyr", "tidyr", "stringr", "purrr", "ggplot2"))

Lifecycle stages

Learn about the lifecycle stages:

A note on vctrs

Quite a few functions have been rewritten to use vctrs package behind the scenes:

dplyr’s if_else(), first(), last(), nth(), coalesce(), between().

The tidyverse team uses vctrs to keep recycling rules and coercion rules in one place.

This doesn’t impact data scientists too much but it means more consistency, better error messages, bug fixes, and higher quality code.

library(dplyr)


Attaching package: 'dplyr'

The following objects are masked from 'package:stats':

    filter, lag

The following objects are masked from 'package:base':

    intersect, setdiff, setequal, union

x <- c(1:10, NA)
if_else(x %% 2 == 0, x, "x")

Error in `if_else()`:
! Can't combine `true` <integer> and `false` <character>.

Base R pipe

You will see a lot of references to the base R pipe:

The 2nd edition of R4DS uses the base pipe so I’ve added a chapter that talks about how to use it, why I think you should use it, and how it differs to %>%: https://t.co/77zwPkg4cd #rstats
