New in VEIN?

No worries! Just install R, Rstudio and then

System requirements

vein imports functions from spatial packages listed below. In order to install these packages, firstly the user must install the requirements mentioned here.

Installation

VEIN can be installed via CRAN or github

install.packages("vein")

gitlab (faster than github)

remotes::install_gitlab("ibarraespinosa/vein")

github

remotes::install_github("atmoschem/vein")

1. get a project (easier)

At the moment, most of the projects covers Brazilian regions, but I will include China, Europe or USA approaches as soon as I can.

Use the function get_project and read the documentation.

library(vein)
?get_project
get_project(directory = "awesome_city")

The structure of the new directory “awesome_city” is:

awesome_city
├── config
│   ├── clean.R
│   ├── config.R
│   ├── inventory.xlsx
│   └── packages.R
├── main.R
├── main.Rproj
├── network
│   ├── net.gpkg
│   └── net.rds
├── scripts
│   ├── evaporatives.R
│   ├── exhaust.R
│   ├── fuel_eval.R
│   ├── net.R
│   ├── pavedroads.R
│   ├── plots.R
│   ├── post.R
│   ├── traffic.R
│   └── wrf.R
└── wrf
└── wrfinput_d02

You have to open the file main.Rproj with Rstudio and then open and run main.R

To run main.R you will need these extra packages:

• ggplot2
• readxl
• eixport (If you plan to generate WRF Chem emissions file)

If you do not have them already, you can install:

install.packages(c("ggplot2", "readxl", "eixport"))
