Automate Data Entry to Online Form using R + Rselenium (or other webdriving tool)

I'm trying to automate adding data from an R data table into a 'Work Order' form on [login to view URL] using Rselenium and R/ Rstudio. The Loc8 platform (and others similar to it) forces users to manually input the data -- Simply put: I want to use webdriving automation to fill in the blanks on the screen. I have several Work Orders that I must load on a daily basis, so a loop that could run off of every row in an excel table would be perfect. The major obstacle here is that these Work Order forms are written in AngularJS, so when you click any input field a wizard pop up appears which allows you to then select a recent input or add a new one). I've just recently started using Rselenium and xpath so I'm quite a bit lost in trying to figure out how to use RSelenium to find the exact elements in the online form I'd like to send data input to. There are 12 fields that need to be updated before the work order form is then saved. Datatypes used are text, date and numeric. So to sum up: 1) I will provide you a table of 'example' data to load onto the page, telling you which field goes where. I will also send you the Rselenium (with chromedriver) code I have so far which leads directly to the input screen/ form. 2) You will write the automation in Rselenium (While I would strongly prefer this is all done in R, I am open to you using another solution that I can leverage for free). 3) You will write another text document explaining how it works, what dependencies exist, any setup that must be performed, etc. So that I can competently run this independently. (Note this will be very much needed if you do not use R). 4) You will send everything to me. I will test your code and reach back out to you if I have any immediate problems getting it to work. Attached is an image of what the platform looks like, along with what pops up when the 'Customer *' field is inspected in chrome browser.
