monitor_collapse: Collapse a ws_monitor Object into a ws_monitor Object with a Single Monitor

Description

Collapses data from all the monitors in ws_monitor into a single-monitor ws_monitor object using the function provided in the FUN argument. The single-monitor result will be located at the mean longitude and latitude unless longitude and latitude parameters are specified.

Any columns of meta that are common to all monitors will be retained in the returned ws_monitor meta.

Usage

monitor_collapse(ws_monitor, longitude = NULL, latitude = NULL,
  monitorID = "generated_id", FUN = mean, na.rm = TRUE, ...)

Arguments

ws_monitor

ws_monitor object.

longitude

Longitude of the collapsed monitoring station.

latitude

Latitude of the collapsed monitoring station.

monitorID

Monitor ID assigned to the collapsed monitoring station.

FUN

Function to be applied to all the monitors at a single time index.

na.rm

Logical specifying whether NA values should be ignored when FUN is applied.

...

additional arguments to be passed on to the apply() function.

Value

A ws_monitor object with meta and data that for the the collapsed single monitor

# NOT RUN {
N_M <- Northwest_Megafires
# monitor_leaflet(N_M) # to identify Spokane monitorIDs
Spokane <- monitor_subsetBy(N_M, stringr::str_detect(N_M$meta$monitorID,'^53063'))
Spokane_min <- monitor_collapse(Spokane, monitorID='Spokane_min', FUN=min)
Spokane_max <- monitor_collapse(Spokane, monitorID='Spokane_max', FUN=max)
