Hi everyone:
It is probably something simple but I can't find anything related to this. Could someone show me how to format the sum of x. the result is 10000 but I need comma formatted like this: 10,000. Since I am going to be using this number to be added to another calculation, I want to be able to remove the comma from the 10,000 value. Thanks

x <- c(2000,3000,5000)
this is the sum of x: \Sexpr{sum(x)}
