Qubole notebook cannot find function

I have successfully installed tidymodelsto a environment in Qubole running SparkR. The notebook does not appear to see the package using devtools::session_info().

When I run mutate_at in the code below I receive the error following. Is anyone familiar with running SparkR in a Qubole environment?

results_df_clean_1 <- mutate_at(residence_data, vars(hoods_in_cluster:hist_invites_created), funs(ifelse(is.na(.),median(., na.rm = TRUE),.)))

Error in mutate_at(residence_data, vars(hoods_in_cluster:hist_invites_created), : could not find function "mutate_at"
