Thank you for reading my problem.

I am running a training exercise and an error says it cannot find my data. Can you help me find it?

Here is the specific error message

Error: object 'Surv_clean' not found

A clean version of the offending code that created the error is pasted below.

# make the minimal dataset
#surv_raw %>% 
#  head(5) %>%                      # take the top 5 rows only
#  select(adm3_name_res, sex) %>%   # keep only the relevant columns
#  dpasta()                         # convert to stand-alone R code

Hey Jim!

The error means R cannot find an object named Surv_clean in your current session.

In the code you shared, Surv_clean is never created.

This is likely an object name mismatch, if you created surv_clean but later wrote Surv_clean, you’ll get:

Error: object 'Surv_clean' not found

Remember that R is case sensitive! please check the variable name and let me know if that was it!

Best,

Luis
