The attached document refers. I have recently attended an introduction course to R, and now wish to apply the program into my work analysis.
The spreadsheet contains water quality data sampled from different locations within a catchment.
I wish to group the variables per point (Point Name), Year (all samples per year eg 1985 etc) These should be averages of each year. Lastly, I wish to plot graphs of all the chemical variables from 1985-2006 to analyze the trends in the concentration of water in the area.
I would like to request your assistance in developing the required commands.
Thanking you in advance.
