I have suddenly run into the issue where any time that I specifically try to use group_by and then mutate, the output is only NAs. If I run the same exact code on a co-worker's workspace, the output is as expected. All other functions that I use are working normally. I have tried detaching and reloading libraries. I have tried using a new workspace and recreating all data frames, and code that previously worked for me no longer has the correct output. I am using R version 3.4.4. Would appreciate any help! Here are examples of code that previously worked fine and now returns only NA for all output.
ventfile <- ventfile %>%
group_by(mrn, hsp_account_id) %>%
mutate(fourdays=ifelse(max(Interval)-min(Interval) > 95,1,NA))
and
ventfile24 <- ventfile %>%
group_by(mrn, hsp_account_id) %>%
filter(row_number()<=24) %>%
mutate(SetRR2=mean(`Set Respiratory Rate`))
