meteo_coverage: Determine the "coverage" for a station data frame

In rnoaa: 'NOAA' Weather Data from R

Determine the "coverage" for a station data frame

Description

Call this function after pulling down observations for a set of stations to retrieve the "coverage" (i.e. how complete each field is). If either or both obs_start_date or obs_end_date are specified, the coverage test will be limited to that date range.

Usage

meteo_coverage(
  meteo_df,
  obs_start_date = NULL,
  obs_end_date = NULL,
  verbose = FALSE
)

Arguments

meteo_df	a meteo data.frame
obs_start_date	specify either or both (obs_start_date, obs_end_date) to constrain coverate tests. These should be Date objects.
obs_end_date	specify either or both (obs_start_date, obs_end_date) to constrain coverate tests. These should be Date objects.
verbose	if TRUE will display the coverage summary along with returning the coverage data.frame

Value

a list containing 2 data.frames named 'summary' and 'detail'. The 'summary' data.frame contains columns:

$ id         (chr)
$ start_date (time)
$ end_date   (time)
$ total_obs  (int)

with additional fields (and their coverage percent) depending on which weather variables were queried and available for the weather station. The data.frame named 'detail' contains the same columns as the meteo_df input data, but expands the rows to contain NAs for days without data.
