trimObs: Trims a dataframe of missing values at the beginning and end

In CentreForHydrology/CRHMr: Pre- and post- processing for CRHM

Trims a dataframe of missing values at the beginning and end

Description

Removes values before 01:00 on the first complete day of the data, and after 00:00 on the last complete rows. Because it is destructive, this command should only be used immediately before exporting observations to a CRHM .obs file. For daily obs, removes values before the first complete row and after the last complete row.

Usage

trimObs(obs, quiet = TRUE, logfile = "")

Arguments

obs	Required. A CRHMr obs dataframe.
quiet	Optional. Suppresses display of messages, except for errors. If you are calling this function in an R script, you will usually leave quiet=TRUE (i.e. the default). If you are working interactively, you will probably want to set quiet=FALSE.
logfile	Optional. Name of the file to be used for logging the action. Normally not used.

Value

If successful, returns the trimmed dataframe. If unsuccessful, returns FALSE.
