Extracting netcdf data based on a shapefile in R

[@gaby441-x6r]

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??
