I can't seem to load the rds file and I'm not sure why. The data and RMarkdown file are saved in the Oregon Schools project. Here is my code and error message:
Error in gzfile(file, "rb") : cannot open the connection In addition: Warning message: In gzfile(file, "rb") : cannot open compressed file '/data/enrollment_race_ethnicity.rds', probable reason 'No such file or directory'

I run this code and get this error message, what am I doing wrong?
Error in filter(., district == "Beaverton SD 48J") : object 'enrollment_by_race_ethnicity' not found
Please advise - I was able to read the rds data and I can see it in the environment pane, but when I use the same code that you shared, I get an error, it says object not found, even though I can see the data on the environment frame.

Thank you, Mychal

Hi David, I got blank chart when running below code... Not sure what is wrong enrollment_by_race_ethinicity %>% filter(year=="2018_2019") %>% filter(district=="Beaverton SD 48J") %>% mutate(percent_of_total_at_school=percentage_of_students) %>%
view()
ggplot(aes(x=percent_of_total_at_school,y=race_ethinicity)) geom_col()
