I do not have missing values but when I write "TempAvRaster_2 = extract(TempAvRaster_1, polygonpro, fun="mean", na.rm=TRUE, df=TRUE)"; I get: Error in if (x@file@nodatavalue < 0) { : missing value where TRUE/FALSE needed". Any help please??

Thank you for your video

The ALT, D and P shouldn't be pressed simultaneously. Rather press the ALT and D, then press P. The Wizard will show.

Very helpful and clear. Thank you very much. Appreciate it

It's really helpful. Thanks for sharing!

Interesting work. However, the audio quality was not clear. Is there a way I can get in touch with you with some questions?

I installed ftools and ivreghdfe, and when I ran reghdfe, I got the error 'command unrecognized.' So, I installed reghdfe as well, and now I got the error invalid syntax (error occurred while loading reghdfe.ado). I am using STATA 14.0 for your information. Do you know why this is happening?

Send the command please.

Hello, Can you please explain to collapse hourly observations into (total) daily observations

Hello, I was wondering to know how you apply a filter on time dimension of NetCDF file? e.g. create a new file for 3 months of a NetCDF file that covers an entire year.

Insightful video. Please how can you do the lag selection analysis/test for panel data in Stata?

Thank you

Thank you so much. it was helpful
