I'd like to know how to analyse data by using R.
I attached a sample file (csv). I made this csv file with data from short period but I have much longer data so I'd like to know how to analyse.
I want to compute
1) average of CM1-10, CM2-10, CM3-10 by day -> named CM10
2) average of CM1-30, CM2-30, CM3-30 by day -> named CM30
* 1,2,3 are numbers indicating replications (n=3) so that I'd like to make them average value.
and then to make a plot how to change those average values with time.
Also, I'd like to put a bar to indicate the maximum and minimum value of each day on the graph line.
It's not been a long time since I started to learn R, so you may consider me as a totally beginner.
Help me please !
I'm not sure why your data has multiple rows for each day (maybe these are for each hour?). But anyway, if you need to average across all the rows of each day, then here is a slightly modified version of Jochen's code to do that:
