I'm following along with data analytics course from google. I am getting this error when running this pipe. I can't find a solution. I need help to understand what is going on. I believe that it maybe that the function is not loaded from a package?
filtered_toothgrowth <- ToothGrowth %>%
- filter(dose==0.5) %>%
- group(supp) %>%
- summarize(mean_len = mean(len,na.rm = T),.group="drop")
Error in group(., supp) : could not find function "group"
