Hi, I am new to R. I'd like to gather the iris data set into a table that looks like this: Species Component Quantity Value setosa Sepal Length 5.1 setosa Sepal Length 4.9 ... How should I use gather()? Thanks in advance for any help.

library(tidyverse) iris %>% as_tibble() %>% # not required gather("Component", "Value", -Species) %>% separate(Component, c("Component", "Quantity"), sep = "\\.") You've stumbled on an issue introduced by regex. A single "." means any single character. The two "\" backslashes "escape" …
