Thanks for catching this. Originally dt_left_join()
used join_mold()
, but it turns out it's a little bit slower than the direct data.table translation.
I'll work on this one, and I'll let you know when it's all fixed. Hopefully today, but it might be tomorrow
from tidytable.
All set.
library(tidytable)
iris_dt <- iris %>%
select.(Species, Sepal.Length)
iris_2_dt <- iris %>%
select.(Species, Petal.Length) %>%
rename.(Species_2 = Species)
left_join.(iris_dt, iris_2_dt, by = c("Species" = "Species_2"))
#> Species Sepal.Length Petal.Length
#> 1: setosa 5.1 1.4
#> 2: setosa 5.1 1.4
#> 3: setosa 5.1 1.3
#> 4: setosa 5.1 1.5
#> 5: setosa 5.1 1.4

Note that dt_left_join()
works, I just personally prefer the verb.()
syntax.
