cannot knit in r due to "Error: could not find function "%>%" "

Question

every time I knit in R with the code below,

dataset_select %>% 
  group_by(V___DXONSPREPORT) %>%
  summarise(cnt = n()) %>% 
  arrange(desc(cnt)) 

the same message "Error: could not find function "%>%" pops up. I have loaded the librarys dplyr and magrittr. Thanks in advance.

Answer 1

You can use install.packages('magrittr') to download the package into R. Then use library(magrittr) to use the package that you downloaded. There are also several other packages that use the pipe function %>% such as stingr and tidyr.
