R studio events update#
observeEvent and eventReactive provide straightforward APIs for event handling that wrap observe and isolate. Welcome to RStudio Community Monthly Events Roundup, where we update you on upcoming events happening at RStudio this month.
CascadiaRConf 2021 (June 4 - 5), a jewel of a regional R conference for its first three years, was canceled in 2020. These situations demand a more imperative, 'event handling' style of programming that is possible-but not particularly intuitive-using the reactive programming primitives observe and isolate. # count() is a convenient way to get a sense of the distribution of # values in a dataset starwars %>% count ( species ) #> # A tibble: 38 × 2 #> species n #> #> 1 Aleena 1 #> 2 Besalisk 1 #> 3 Cerean 1 #> 4 Chagrian 1 #> 5 Clawdite 1 #> 6 Droid 6 #> 7 Dug 1 #> 8 Ewok 1 #> 9 Geonosian 1 #> 10 Gungan 3 #> # … with 28 more rows starwars %>% count ( species, sort = TRUE ) #> # A tibble: 38 × 2 #> species n #> #> 1 Human 35 #> 2 Droid 6 #> 3 NA 4 #> 4 Gungan 3 #> 5 Kaminoan 2 #> 6 Mirialan 2 #> 7 Twi'lek 2 #> 8 Wookiee 2 #> 9 Zabrak 2 #> 10 Aleena 1 #> # … with 28 more rows starwars %>% count ( sex, gender, sort = TRUE ) #> # A tibble: 6 × 3 #> sex gender n #> #> 1 male masculine 60 #> 2 female feminine 16 #> 3 none masculine 5 #> 4 NA NA 4 #> 5 hermaphroditic masculine 1 #> 6 none feminine 1 starwars %>% count (birth_decade = round ( birth_year, - 1 ) ) #> # A tibble: 15 × 2 #> birth_decade n #> #> 1 10 1 #> 2 20 6 #> 3 30 4 #> 4 40 6 #> 5 50 8 #> 6 60 4 #> 7 70 4 #> 8 80 2 #> 9 90 3 #> 10 100 1 #> 11 110 1 #> 12 200 1 #> 13 600 1 #> 14 900 1 #> 15 NA 44 # use the `wt` argument to perform a weighted count. Upcoming Events NICAR 2021 (March 3 - 5), the Investigative Reporters & Editors Conference on data journalism should be well attended by data journalists using R for their everyday reporting.
