Deprecated static directional analysis functions

Static direction analysis mapping functions have been deprecated in favour of combined functions (e.g., polarMap()), which present a more consistent, unified API for users to simply swap between the two output formats.

Arguments

data

Input data table with pollutant, wind, and geo-spatial information.

required | scope: dynamic & static

A data frame. The data frame must contain the data to plot the directional analysis marker, which includes wind speed (ws), wind direction (wd), and the column representing the concentration of a pollutant. In addition, data must include a decimal latitude and longitude (or X/Y coordinate used in conjunction with crs).

pollutant

Pollutant name(s).

required | scope: dynamic & static

The column name(s) of the pollutant(s) to plot. If multiple pollutants are specified and a non-pairwise statistic is supplied, the type argument will no longer be able to be used and:

Dynamic: The pollutants can be toggled between using a "layer control" menu.
Static:: The pollutants will each appear in a different panel.

Multiple pollutants prohibit the use of the type argument for non-pairwise statistics.

x

The radial axis variable.

default: "ws" | scope: dynamic & static

The column name for the radial axis variable to use in openair::polarPlot(). Defaults to using wind speed, "ws", but other meteorological variables such as ambient temperature or atmospheric stability may be useful.

limits

Specifier for the plot colour scale bounds.

default: "free" | scope: dynamic & static

One of:

"fixed" which ensures all of the markers use the same colour scale.
"free" (the default) which allows all of the markers to use different colour scales.
A numeric vector in the form c(lower, upper) used to define the colour scale. For example, limits = c(0, 100) would force the plot limits to span 0-100.

upper

Specifier for the polar plot radial axis upper boundary.

default: "fixed" | scope: dynamic & static

One of:

"fixed" (the default) which ensures all of the markers use the same radial axis scale.
"free" which allows all of the markers to use different radial axis scales.
A numeric value, used as the upper limit for the radial axis scale.

latitude, longitude

The decimal latitude(Y)/longitude(X).

default: NULL | scope: dynamic & static

Column names representing the decimal latitude and longitude (or other Y/X coordinate if using a different crs). If not provided, will be automatically inferred from data by looking for a column named "lat"/"latitude" or "lon"/"lng"/"long"/"longitude" (case-insensitively).

crs

The coordinate reference system (CRS).

default: 4326 | scope: dynamic & static

The coordinate reference system (CRS) of the data, passed to sf::st_crs(). By default this is EPSG:4326, the CRS associated with the commonly used latitude and longitude coordinates. Different coordinate systems can be specified using crs (e.g., crs = 27700 for the British National Grid). Note that non-lat/lng coordinate systems will be re-projected to EPSG:4326 for plotting on the map.

provider

The basemap(s) to be used.

default: "OpenStreetMap" | scope: dynamic & static

The base map(s) to be used beneath the polar markers. If not provided, will default to "OpenStreetMap"/"osm" for both dynamic and static maps.

Dynamic: Any number of leaflet::providers. See http://leaflet-extras.github.io/leaflet-providers/preview/ for a list of all base maps that can be used. If multiple base maps are provided, they can be toggled between using a "layer control" interface. By default, the interface will use the provider names as labels, but users can define their own using a named vector (e.g., c("Default" = "OpenStreetMap", "Satellite" = "Esri.WorldImagery"))
Static: One of rosm::osm.types().

There is some overlap in static and dynamic providers. For example, {ggspatial} uses "osm" to specify "OpenStreetMap". When static providers are provided to dynamic maps or vice versa, {openairmaps} will attempt to substitute the correct provider string.

facet

Passed to the type argument of the relevant polarMap() family function.

cols

Colours to use for plotting.

default: "turbo" | scope: dynamic & static

The colours used for plotting, passed to openair::openColours(). The default, "turbo", is a rainbow palette with relatively perceptually uniform colours.

alpha

Transparency value for polar markers.

default: 1 | scope: dynamic & static

A value between 0 (fully transparent) and 1 (fully opaque).

key

Draw individual marker legends?

default: FALSE | scope: dynamic & static

Draw a key for each individual marker? Potentially useful when limits = "free", but of limited use otherwise.

facet.nrow

Passed to the static.nrow argument of the relevant polarMap() family function.

d.icon

The diameter of the plot on the map in pixels.

default: 200 | scope: dynamic & static

This will affect the size of the individual polar markers. Alternatively, a vector in the form c(width, height) can be provided if a non-circular marker is desired.

d.fig

The diameter of the plots to be produced using {openair} in inches.

default: 3.5 | scope: dynamic & static

This will affect the resolution of the markers on the map. Alternatively, a vector in the form c(width, height) can be provided if a non-circular marker is desired.

...

Passed to the polar plotting function

before

A data frame that represents the "before" case. See polarPlot() for details of different input requirements.

after

A data frame that represents the "after" case. See polarPlot() for details of different input requirements.

period

Temporal period for radial axis.

default: "hour" | scope: dynamic & static

Options are "hour" (the default, to plot diurnal variations), "season" to plot variation throughout the year, "weekday" to plot day of the week variation and "trend" to plot the trend by wind direction.

ws.int

The wind speed interval of the colour axis.

default: 2 | scope: dynamic & static

The wind speed interval. Default is 2 m/s but for low met masts with low mean wind speeds a value of 1 or 0.5 m/s may be better.

breaks

Specifier for the number of breaks of the colour axis.

default: 4 | scope: dynamic & static

Most commonly, the number of break points for wind speed in openair::windRose(). For the ws.int default of 2, the default breaks, 4, generates the break points 2, 4, 6, and 8. Breaks can also be used to set specific break points. For example, the argument `breaks = c(0, 1, 10, 100)“ breaks the data into segments <1, 1-10, 10-100, >100.

statistic

The statistic to be applied to each data bin in the plot

default: "prop.mean" | scope: dynamic & static

Options currently include "prop.count", "prop.mean" and "abs.count". "prop.count" sizes bins according to the proportion of the frequency of measurements. Similarly, "prop.mean" sizes bins according to their relative contribution to the mean. "abs.count" provides the absolute count of measurements in each bin.

percentile

The percentile values for the colour scale bin.

default: c(25, 50, 75, 90, 95) | scope: dynamic & static

The percentile value(s) to plot using openair::percentileRose(). Must be a vector of values between 0 and 100. If percentile = NA then only a mean line will be shown.

intervals

Specifier for the percentile rose radial axis intervals.

default: "fixed" | scope: dynamic & static

One of:

"fixed" (the default) which ensures all of the markers use the same radial axis scale.
"free" which allows all of the markers to use different radial axis scales.
A numeric vector defining a sequence of numbers to use as the intervals, e.g., intervals = c(0, 10, 30, 50).

Value

a ggplot2 object using ggplot2::coord_sf() coordinates with a ggspatial basemap
