flux_match {fluxible} | R Documentation |
Matching continuously measured fluxes with measurement IDs and meta data
Description
Matching a dataframe of continuously measured
gas concentration data with measurement metadata from another dataframe.
Measurements are paired with their metadata based on datetime.
Extra variables in both dataframes are kept in the output.
Usage
flux_match(
raw_conc,
field_record,
f_datetime,
start_col,
end_col,
measurement_length,
fixed_length = TRUE,
time_diff = 0,
startcrop = 0,
ratio_threshold = deprecated(),
f_conc = deprecated()
)
Arguments
raw_conc |
dataframe of CO2 concentration measured continuously.
Has to contain at least a datetime column in ymd_hms format and
a gas concentration column as double.
|
field_record |
dataframe recording which measurement happened when.
Has to contain at least a column containing the start of each measurement,
and any other column identifying the measurements.
|
f_datetime |
datetime column in raw_conc (ymd_hms format)
|
start_col |
start column in field_record (ymd_hms format)
|
end_col |
end columne in field_record (ymd_hms format).
Only needed if fixed_length = "FALSE" .
|
measurement_length |
length of the measurement (in seconds)
from the start specified in the field_record
|
fixed_length |
if TRUE (default), the measurement_length is used to
create the end column. If FALSE , end_col has to be provided.
|
time_diff |
time difference (in seconds) between the two datasets.
Will be added to the datetime column of the raw_conc dataset.
For situations where the time was not synchronized correctly.
|
startcrop |
startcrop is no longer
supported. Please use start_cut in flux_fitting instead.
|
ratio_threshold |
ratio_threshold
is no longer supported. Please use ratio_threshold in flux_quality
instead.
|
f_conc |
f_conc is no longer
required
|
Value
a dataframe with concentration measurements, corresponding datetime,
flux ID (f_fluxid
), measurements start (f_start
) and end (f_end
).
Examples
data(co2_df_short, record_short)
flux_match(co2_df_short, record_short, datetime, start,
measurement_length = 180)
