Is there way to merge column output when using readNWISuv?
Created by: sbrady-usgs
I have a site where one sensor is discontinued for another. These were assigned different DD numbers and returned in separate columns by readNWISuv. Is there an easy way in R to merge the two into one column filling in the missing values? Here is an example of such a site:
In this case, fill 96_63680 when 44_63680 is missing a value.
Thanks, Steve
