Dear Sir/madam
I am a new user to R. I have no background in coding or even
scripting. It seems as if R would be the best tool in order to analyse
large sets of data. I need to sum hourly readings for the day and then
sum daily into monthly readings. i also need to do the same for
another set of data, but average instead of sum. How do I do this?
Rather than asking for a tutorial on data management, you should:
a) read some introductory texts (look for "contributed" at the main r-
project site)
b) read the Posting Guide [ ... or reverse a) and b) ]
c) construct a prototypical data object in R and using the skills
exemplified in hte Posting Guide post a minimal example of what you
are starting with and what you expect.
