Overview

megamation provides an R interface to Megamation DirectLine via the API.

Installation

You can install the released version of megamation from CRAN with:

install.packages("megamation")

And the development version from GitHub with:

# install.packages("pak")
pak::pak("asadow/megamation")

Attach megamation

Authorization

You have two options.

Either use mm_authorize():

mm_authorize(
  key = "<YOUR-MEGAMATION_KEY>",
  url = "<YOUR-MEGAMATION_URL>"
)

Or run usethis::edit_r_environ() to install your API credentials in your .Renviron.

MEGAMATION_KEY = '<YOUR-MEGAMATION_KEY>'
MEGAMATION_URL = '<YOUR-MEGAMATION_URL>'

Now megamation functions will automatically use your credentials, so you don’t have to expose them in your code.

Grabbing Data

mm_data() downloads data from your tables into R.

mm_data("status")
#> ℹ Requesting...
#> # A tibble: 9 × 3
#>   ampc_required description                              status
#>   <chr>         <chr>                                    <chr> 
#> 1 No            ADMIN HTML WORK ORDERS WAITING TO SCREEN AW    
#> 2 Yes           Cancelled                                CA    
#> 3 No            CLOSED                                   CL    
#> 4 No            INITIATED                                I

#> 7 No            SCHEDULED                                S     
#> 8 No            TRANSFERED                               T     
#> 9 Yes           Waiting for Trade                        WT

It provides informative R errors (alongside HTTP errors).

#> ℹ Requesting...
#> ℹ NB: 1/1 requests returned errors or no data.

Filtering

mm_data() allows you to easily filter by fields (columns).

Available Filters

mm_names() allows you to see the columns that can act as filters.

mm_names("workorder")
#> # A tibble: 39 × 4
#>    field           filter_enabled description               type          
#>    <chr>           <lgl>          <chr>                     <chr>         
#>  1 type            TRUE           Type                      VARCHAR(65531)
#>  2 status          TRUE           Status                    VARCHAR(65531)
#>  3 date            TRUE           Date - [Month][Day][Year] DATE          
#>  4 submitted_by    TRUE           Submitted By              VARCHAR(65531)
#>  5 priority        TRUE           Priority                  VARCHAR(65531)
#>  6 building_id     TRUE           Building                  VARCHAR(65531)
#>  7 eqp_no          TRUE           Equipment#                VARCHAR(65531)
#>  8 assign_to       TRUE           Assign To                 VARCHAR(65531)
#>  9 issue_to        TRUE           Issue To                  VARCHAR(65531)
#> 10 contractor_name TRUE           Contractor Name           VARCHAR(255)  
#> # ℹ 29 more rows

Modifiers

You can use Megamation’s modifiers on filter values.

  • [] for containing

  • !! for not equal

  • >> for greater than

  • << for less than

  • <> for between.

For example, supply <field> = "[]<value>" to get rows where <field> contains <value>. Here’s how you would request all work orders containing trades ADMIN and IT.

admin_and_it <- c("[]ADMIN", "[]IT")

mm_data("workorder", trade = admin_and_it)
#> # Data Not Shown for Privacy

Dates

Avoid <> for dates. Instead, use a sequence of R Date’s. Here’s how you would request all work orders from January, 2023.

jan_2023 <- seq.Date(
  as.Date("2023-01-01"),
  as.Date("2023-01-31"),
  by = "day"
)

mm_data("workorder", date = jan_2023)
#> # Data Not Shown for Privacy
