Calculate daily means from 5-minute interval data
Hi Rich, Your request is a bit open-ended but here's a suggestion that might help get you an answer. Provide dummy data (e.g. 5-10 lines), say like the contents of a csv file, and calculate by hand what you'd like to see in the plot. (And describe what the plot would look like.) It sounds like what you want could be done in a few lines of R code which would work both on the dummy data and the real data.

I have a year's hydraulic data (discharge, stage height, velocity, etc.) from a USGS monitoring gauge recording values every 5 minutes. The data files contain 90K-93K lines and plotting all these data would produce a solid block of color. What I want are the daily means and standard deviation from these data. As an occasional R user (depending on project needs) I've no idea what packages could be applied to these data frames. There likely are multiple paths to extracting these daily values so summary statistics can be calculated and plotted. I'd appreciate suggestions on where to start to learn how I can do this. TIA, Rich
