embrs generics

Functions to build vehicle, fleet and route objects for use in embrs emission models.

Usage

# S3 method for embrs
+(e1, e2, ...)

# S3 method for embrs
*(e1, e2, ...)

# S3 method for embrs
print(x, ...)

# S3 method for embrs
plot(x, plot.type = "by.em", em.type = "all", ...)

# S3 method for embrs_vehicle
print(x, ...)

# S3 method for embrs_route
print(x, ...)

# S3 method for embrs_model
print(x, ...)

Arguments

e1, e2

The objects to add or multiple when building an emission inventory

...

Additional arguments, sometimes ignored.

x

The object to print, plot, etc.

plot.type

(for plot only, character) the type of plot to generate, options: 'by.em' standard plot; 'by.vehicle'. See Note. NULL to disable/show all emissions types calculated.

em.type

(for plot only, character) the emissions to generate plot for, options: 'all' for all emissions types, or 'just.pm' for just particulates. See Note.

Value

These functions make vehicle and fleet class embrs objects.

Note

These functions are in development, so please be aware that options outputs may change significantly. plot.type = 'by.vehicle' and em.type = 'just.pm' produces plots like those used in Tivey el al (2023) to compare particulate emissions from different buses types.
