Neal Richardson commented on ARROW-6348:
----------------------------------------
It's a namespace issue. That shouldn't error and I can make it work, but you
can solve this now by just loading {{library(arrow):}}
{code:r}
> write.csv(iris, "iris.csv")
> test <- arrow::read_csv_arrow("iris.csv")
Error in read_delim_arrow(file = "iris.csv", delim = ",") :
could not find function "read_delim_arrow"
> library(arrow)
Attaching package: ‘arrow’
The following object is masked from ‘package:utils’:
timestamp
> test <- read_csv_arrow("iris.csv")
> head(test)
