What does %>% mean in R?

Question

I am following this example, the *server.R*, [file is here](https://github.com/wch/movies/blob/master/server.R#L32).I plan to do a similar filter, but am lost as to what `%>%` does. # Apply filters m <- all_movies %>% filter( Reviews >= reviews, Oscars >= oscars, Year >= minyear, Year <= maxyear, BoxOffice >= minboxoffice, BoxOffice <= maxboxoffice ) %>% arrange(Oscars)

Answer 1

This is called infix operator %>% which is not the part of base R, but is in fact defined by the package magrittr (CRAN) and is heavily used by dplyr (CRAN) and Tidyverse packages of R.
