The dataset has fillvalue of 1e30. While taking mean of the NetCDF files what code should i use?
list <- list.files("/filepath/", pattern = "*.nc", full.names = TRUE) u2 <- stack(list) r <- mean(u2, na.rm=TRUE)
I am getting
values : -7.53555e+18, 1.263985e+18 (min, max) using
-7.781048e+16, 3.923543e+15 (min, max) while coding with
r <- mean(u2).
na.rm=TRUE does not give the correct result as the data are exaggerated. Another problem is that I am unable to plot the mean from first method (na.rm=FALSE) although the values seems to be quite correct. Before making analysis and plotting of the data what should be done?
