Please, I installed the RStudio Version 1.2.1335 and R version 3.6.1on my MacBook Pro.
However, I keep receiving the "Error: object 'a' not found" despite defining the object.
I type "a", then "print(a)" also but its the same outcome.
I try doing other things like finding log(8) and 2^3 and it returned the values without an error message.
I downloaded the library (dslabs) and I called it at the beginning, not sure if that is necessary though.
Also when I type in ls() to see the object saved in the workspace, it returns
> ls() character(0)
I am not sure what I did wrong
I need help.
