I am new to R. I am trying to create a simple shiny
application which will display barplot using left drop down input. It
works for me when i have to plot for one drop down. however, it does not
work for multiple drop down.
I have three columns in my dataframe
- Country -
requirement is when I select “Region” it should plot region (EMEA,
Asia, Americas) specific rating. and when I select Country (I.e.India,
Maxico, China, Spain etc ) it should show country specific rating. All
in bar graph.
Yes, The drop down should be dependent to each other. Please suggest me with some examples.
Thanks in advance.
