gmRi

The goal of {gmRi} is to consolidate useful research tools under one consistent repository. Things like official GMRI colors or style sheets for Rmarkdown documents are easy first steps in creating consistent and professional looking documents. Consistent work flows for creating datasets from outside sources like from satellite SST or NERACOOS buoy arrays will make our work take less time and be consistent in-house.

Installation

You can install the development version of gmRi from GitHub with:

devtools::install_github("https://github.com/gulfofmaine/gmRi")

This package is stored on a private repository, and in order to access it through devtools::install_github() a github personal access token needs to be available in your R system environment. If you are getting the following error message you either do not have access to this private repository or you need to set your github PAT:

Error: Failed to install ‘unknown package’ from GitHub:
  HTTP error 404.
  Not Found
  Did you spell the repo owner (`gulfofmaine`) and repo name (`gmRi`) correctly?
  - If spelling is correct, check that you have the required permissions to access the repo.
  ```


To check your R system environment for your github PAT run `Sys.getenv()` in the R console and look for `GITHUB_PAT`. If there is no `GITHUB_PAT` set in your system environment, you can generate a new token in your browser at [github](https://github.com/settings/tokens), with more detailed instructions at [Happy git with R](https://happygitwithr.com/github-pat.html). 

Once a new token is generated, you will need to add it to your R system environment. Typing `usethis::edit_r_environ()` will open a new tab in Rstudio called ".Renviron". In that new file you will assign your GITHUB_PAT by typing: 

GITHUB_PAT=my_new_github_access_token_copied_from_the_browser

Save the .Renviron file, and restart your R session. Your Github personal access token should now be visible when you type: `Sys.getenv()`.

After the personal access token (PAT) is set you should be able to install the package (assuming you have access to the gulfofmaine github).


## Example

This is a basic example of how to pull GMRI colors for a ggplot2 figure:

```r
library(gmRi)
library(ggplot2)
## basic example code

ggplot(mtcars, aes(hp, mpg)) +
  geom_point(color = gmri_cols("gmri blue"), size = 4, alpha = .8)

If you want to use a gmri color palette you can access them this way:

ggplot(mpg, aes(manufacturer, fill = manufacturer)) +
   geom_bar() +
   theme(axis.text.x = element_text(angle = 45, hjust = 1)) +
   scale_fill_gmri(palette = "mixed", guide = "none")
