This is old but excellent. It is base R stuff and I am more interested in using the tidyverse for R but still this is excellent. It is not so much the code but rather that you walk the viewer through what your a doing rather than showing off coding skills. Also there is a point to the project. I did run into some issues when I tried to carve out a small geographic region and run the image.plot on it. It broke stating that there was an error in z (time) stating the nlevel - from must be finite number.

Thanks for the help. What if my variable tm has units of hours since 1950-01-01 instead of seconds since 1970-01-01? I tried to modify that part in my script, but I get wrong dates. The dates i downloaded were from 2015-03-01 to 2015-03-31 (31 dates in total), and the dates i get from the as.POSIXct function are all from 1950-01-07 at diferent times in the same day.

Great video ! Thank you. Any ideas of why the map() function is not working for me? image.plot() plot without issue but when I try to add map(add=T) I get: Error in map(add = T) : argument ".x" is missing, with no default.

If you had a lot of data in a vector, then length() will return the data and length(unique()) will return how many unique vector values are in the vector

Hi! Your video is really helpful! It helps me to know other NetCDF files. I have two questions, could you help me: 1. The latitude in my original data is from 90 to -90. When I want to draw the world image "image.plot(lon,-lat,AET)", I have to put a negative to make this script work, but then the map was flipped (north in the bottom). 2. In the "image.plot(E_ts[,,1])", If I just import one grid, the dimension would be just 1 (only time => __ __ 365, otherwise I add one unit of length => 2 2 365). Is there any ways I can make it => 1 1 365? Thank you in advance!

How would you reduce the time window for the times series, say if I wanted 1900-01-15 to 1999-12-15? When I enter the 3rd dimension's position of the first date (241) and the count needed to take me to the second date (1199) into the anom_ts <- ncvar_get(), I get an error on the plot for the time series "'x' and 'y' lengths differ," having changed nothing else.
