Lab 4 - Issues with selectInput

[kpearce6]

Hi @jamisoncrawford. I was hoping you could help me with an issue I am having with Lab 4. Whenever I try to run my code, it always stops at the first selectInput and produces an error that says "could not find function "selectInput". I have tried many different inputIDs as well as looking at the code and not sure if I am just missing something. I have this included as a chunk before renderPlot. Here is currently what I have for the selectInput function:

selectInput(inputId='Teams',  
             label='Choose a Team',   
             choices=c("Cincinnati Reds","Pittsburg Pirates","Philadelphia Phillies","St. Louis Cardinals","Chicago White Sox","Detroit Tigers","Chicago Cubs","Boston Red Sox","New York Yankees","Cleveland Indians"),  
             selected="Cincinnati Reds"   
           )

Thanks!
Katie

Hi @kpearce6, this code looks perfectly fine! Have you loaded Shiny with library(shiny) at the very beginning of your .R script?

If your error message says that it cannot recognize an object, and that object is a function, it typically means that R hasn't been told to load the package that contains that function. Let me know if that helps and sorry for the delay!

Hi @jamisoncrawford. Thanks for getting back to me. I tried my code on another computer and it worked so not sure what happened. It should be all good now. I appreciate it!

@kpearce6 well that's interesting! Figure out why it worked and you'll learn 1% of R 😄

Glad you got it working!

When all else fails, take a nap and try again! Works for the computer too.
