Creating a drop-down list through shiny, using atomic vector

[sami.khamash]

Hi,
I'm working on a simple shiny app and I'm trying to create a drop-down list using one of the columns "Department" (which is a character atomic vector) in the excel data which I imported into RStudio, the code I'm using is as follows:

selectInput("select", "Select Department/Entity",
    choices = unique(Key_Risks["Department"]))

when I run the app, nothing appears in the drop-down list, the only thing that appears is "NA", not the department names!

Your support would be highly appreciated.
Thanks,

Please have a look at these resources, to see how to create one for a shiny app

Shiny debugging and reprex guide

Shiny issues can be challenging to resolve relative to other problems with your code or statistical methods. Shiny apps are often large, complex projects with interacting files. When seeking help from others it is considered polite to: First, do your best to work through RStudio's debugging tools to diagnose your issue on your own. Often those shiny logs and tracebacks are useful to others trying to help out. Second, strive to minimize the effort required to replicate your issue. You can do this with a reproducible example ("reprex"). Shiny Debugging Errors in Shiny code can be difficult to track down. If you don't know where your problem is coming from, you can track it down with some o…
