Shiny reports

[lopierra]

Hi all! I'm new to aggregate and look forward to meeting everyone tomorrow.

What I'm working on:
I work in a research lab at OHSU that collects samples from patients with leukemia, analyzes the samples, and stores the data in a large relational database. I am trying to semi-automate a couple of different types of reports of the data (generally for an audience of non-R users):

1. Drug screening report to email to external collaborators (either as revealjs slides or html report with ggiraph widgets)
2. Monitor for internal purposes how many samples of different types have been collected over specific time periods (using Shiny app)

Code question:
In my Shiny app, I am trying to pre-select an option in checkboxGroupInput using selected =. It should be straightforward, but I keep getting the following error message: Error in if (inline) { : argument is not interpretable as logical

The app works fine if I leave out selected =, so I'm not sure what's going on. I can show my code at the meeting.

General question:
I am new to Shiny and am confused by the many different flavors of Shiny reports. Examples:

• Download from app to parameterized R Markdown document
• Shiny dashboard
• flexdashboard with Shiny widgets
• Shiny documents
• Shiny widgets in a Shiny document?? I don't understand how this is a separate thing

I was wondering which ones you all prefer and why.
