dplyr verbs: conclusion
R has an amazing set of libraries called the tidyverse. It contains a
set of packages that play well together. A core library in this set is
dplyr which contains verbs to help you analyse data. In this series
of videos we'll give a quick overview of them.
Once again we assume that you've got the dataframe set up appropriately.
library(tidyverse) # This command makes sure that the chickweight dataframe is clean. df <- ChickWeight %>% ungroup() %>% as.data.frame()
You can combine verbs together. Below we're using filter and mutate.
df %>% filter(Diet == 3) %>% mutate(growth = weight/(Time + 1))
