Problem loading data into shiny dashboards

Hello,

I have been struggling in using shiny dashboards in regards of loading data to the application.

My application currently has 3 sources:
load("data1.RData")
load("data2.RData")
load("data3.RData")

Commonly I get errors when loading the app to shiny server and the common message I get:
Error: object 'data3' not found

What is the correct to load data in the app ?
Does having multiple data loading could affect the functionality ?

Appreciate any light on the matter.
