plotTempsByYear: Creates a 'ggplot2' object of daily mean air temps by year

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

Creates a ggplot2 object of daily mean air temps by year

Description

Aggregates air temeratures to mean daily values and creates a ggplot2 faceted by year. Note that this function would work for any other non-cumulative variable, if the Y-axis label is changed.

Usage

plotTempsByYear(obs = "", obsNames = "", tempCols = 1, commonYears = TRUE)

Arguments

obs	Required. Either a CRHMr obs data frame or a list of data frames.
obsNames	Optional. A vector containing names for the data frames. If there are more data frames than names, the data will be named obs 1, obs 2 etc.
tempCols	Optional. Column(s) containing air temperatures. Can be a single value or a vector. Values will be recycled if necessary. Default is 1.
commonYears	Optional. If TRUE (the default) then the range of years will be restricted to the common first and last years.

Value

If successful, returns a faceted ggplot2 object of mean daily air temperatures vs time. If unsuccessful, returns FALSE.
