faceted_time_series_plot2 {puff} | R Documentation |
Alternate version with wind rose at each time step + scatter plot of methane concentration time series
Description
Alternate version with wind rose at each time step + scatter plot of methane concentration time series
Usage
faceted_time_series_plot2(
sensor_concentrations,
sensor_coords,
wind_data,
start_time,
end_time,
output_dt,
text_size = 12
)
Arguments
sensor_concentrations |
Data frame. Output from a sensor simulation function, which must include a column named "Group.1" which contains the timestamps (e.g., "YYYY-MM-DD HH:MM:SS") and a column "Sensor_1" for the sensor concentration values. |
sensor_coords |
A data frame or matrix containing sensor locations. |
wind_data |
A list containing wind data with components u and v |
start_time |
POSIXct. Start time of the simulation. |
end_time |
POSIXct. End time of the simulation. |
output_dt |
Integer. Desired time resolution (in seconds) for the final output of concentrations. |
text_size |
Default at 12. |
Value
A ggplot object with faceted time series plots of methane concentrations and wind rose data.
