Hello there,
I normally get this error when I specified the path incorrectly (perhaps missing a component of the path, like a subdirectory). Could you check that the path in "can't find report file: ~/Desktop/Review_workshop_striped_bass_2019_NewBern_NC/AR_SS_model/model_1/Report.sso" is correct? The path specified in SS_output should be to the folder containing the SS model output files.
Also, your error seems to have an additional directory in the path: u2069, and I am not sure where it came from give the path command you show and error message it produced? Any ideas?
If everything seems fine, but it still won't work, another thing to test is if a path relative to your R working directory will work. For ex, if your R working directory is "~/Desktop/Review_workshop_striped_bass_2019_NewBern_NC/AR_SS_model", you can try specifying the command as SS_output("model_1", covar =TRUE). Will relative path work? Maybe also try forming the path using the r base function file.path instead of forward slashes (although I don't think that should make a difference)?
Given you are using mac and r4ss is typically tested most throughly on windows, it is possible that the treatment of the path in r4ss has issues, so we can investigate that next if you still are having issues.
Thanks,
Kathryn
