Rio -r flag #42

Closed crazyhottommy closed 7 years ago

crazyhottommy commented 9 years ago

-r flag loads the dplyr library, but I got error:

cat iris.csv | Rio -e -r -v "df %>% group_by(species) %>% mean(sepal_length)" Error: object 'r' not found Execution halted cat: /var/folders/h5/3xs5c90n0njgp7n9_qdwwj2m0000gn/T//Rio-OLVgmOU2.err: No such file or directory

-r is being interpreted as the expression. The solution is to move -e right before the expression:

cat iris.csv | Rio -vre "df %>% group_by(species) %>% mean(sepal_length)"
