Hello. I'm very very new to coding and R.
I have an nc4 file which has daily precipitation values for the world from 1970 to 1980. I need the annual precipitation values instead of daily. At the end of the day, I would like to draw maps with the annual precipitation values so I should end up with 10 global maps (one for each year).
I don't know if any of this information might be helpful as I am so new to this and all I've done is print the file to see what's inside but I thought some kind soul willing to help me might want to look at this information.
1 variables (excluding dimension variables):
units: kg m-2 s-1
3 dimensions: lon Size:720 standard_name: longitude long_name: longitude units: degrees_east axis: X lat Size:360 standard_name: latitude long_name: latitude units: degrees_north axis: Y time Size:3653 *** is unlimited *** standard_name: time long_name: time units: days since 1861-1-1 00:00:00 calendar: proleptic_gregorian axis: T
While I was fiddling around, I did get an error saying cannot allocate vector of size 3.5Gb. Does that mean this file is too big to do anything? Do I need to cut it up?
Thank you so much in advance. My apologies for asking such a basic question but I really didn't know where to start.
