The output of my code:
library(IBrokers)
tws <- twsConnect(port=7496)
Error in socketConnection(host = host, port = port, open = "ab", blocking = blocking) :
cannot open the connection
In addition: Warning message:
In socketConnection(host = host, port = port, open = "ab", blocking = blocking) :
localhost:7496 cannot be opened
I have checked my Global Configurations in the TWS. The port is in fact 7496.

I am using the latest of Linux Mint. My IB account has been approved and funded.
It finally worked!. Turns out the "Enable ActiveX and Socket Clients" checkbox was unchecked. I checked it and it worked.
