Multiple time series with zoo
...hanks for everyone's input so far, it is greatly appreciated. But I've got
one last task I could use some advice on
Here are the first few lines of my data set:
site,time_local,time_utc,reef_type_code,sensor_type,sensor_depth_m,temperature_c

line.site,time_local,time_utc,reef_type_code,sensor_type,sensor_depth_m,temp
