Description Usage Arguments Value Examples

Apply measurement cutoff filters and flag filters

filter_sms(
  sms_flagged,
  ghi_cutoff_min = 5,
  ws_cutoff_min = 0.25,
  flagged_data_is_filtered = TRUE
)

`sms_flagged`	Dataframe of sms data with "tidy" variables
`ghi_cutoff_min`	Measured GHI values below this cutoff will be filtered to zero because of poor sensor performance at low values (W/m2)
`ws_cutoff_min`	Measured wind speed values below this cutoff will be filtered to zero (m/s)
`flagged_data_is_filtered`	Whether or not we should filter out the flagged data (Recommended)

SMS Dataframe with zero at all points below the measurement cutoff minimum and NA for all points with flag filters applied
