Hello,

The following works with me.


library(coronavirus)
library(dplyr)

data(coronavirus, package = "coronavirus")
#update_dataset(silence = FALSE)

coronavirus %>%
   select(country, date, type, cases) %>%
   filter(
     country == 'Namibia',
     date == '2021-10-23',
     cases == 357
   )



Can you post the pipe code you are running?

Hope this helps,

Rui Barradas
