{modelscript}
is a
little RStudio add-in I wrote to help me with modelling. I've been
testing out the tidymodels framework for
R (fantastic, btw) and I thought it would be handy to be able to create
a new .R file with all the steps you'd need for most modelling tasks.
You can install it with
`remotes::install_github("RobertMyles/modelscript"). A new RStudio
add-in will appear in the Addins menu that will create your R modelling
script:
For anybody who'd like to make their own RStudio add-in, it was easy to
do. In RStudio, you can create a new section in an .R file with
control shift R
, so I use this basic idea to create a template for all
(or most, depending on the application) of the steps you'd typically use
in any modelling task. Since we can interact with RStudio itself through
rstudioapi,
it was quite straightforward to set it up as an RStudio add-in.
Basically, you create a new R package, create an
inst/rstudio/addins.dcf
file in the package, and fill in the following
four entries:
Name:
Description:
Binding:
Interactive:
Mine is:
Name: modelscript
Description: Creates a modelling script template in a new .R file.
Binding: modelscript
Interactive: false
The Binding is the (R) function it calls, in this case a function called
modelscript()
. This function is quite straightforward, it uses
rstudioapi::documentNew()
to create a new .R file with the text I
wanted used. Once you install modelscript, refresh your Rsession and a
new entry on the RStudio Addins menu will appear, which you can click to
create the .R file as in the GIF above.
The template itlself contains a prep and a model building section. 'prep' contains subsections for:
'Build Model' contains subsections for:
Obviously these might not all be used, or other parts might be needed, or for example, the EDA - tidy - visualize part might be repeated, but it's a nice helper for getting up and running. And you could of course modify it for your own use and then make your own package and add-in. 🤓
