Hey everyone,
I am new to RStudio and I want to plot a time-temperature graph. I want to compare the temperatue of a .txt file and a .nc file in one plot. My problem is that the length differs. I have 288 measurement points, but the temperature of the netcdf has a length of 14450. Why do I have 14450 of temperature, but only 288 time stamps?

The structure of temp_withoutNAs is: num [1:5, 1:5, 1:2, 1:288] 21.9 21.9 21.9 22 22.1 ...
