how to skip executing several lines with if clause in R

Question

how to skip executing several lines of codes if a condition in IF statement is met. Condition happens occasionally so whenever it happens we need to skip executing several lines of codes, for example:

 if ( op=='A) {

     #skip doing everything here }
{

  #some line of codes which will be run in any condition

or is it possible to do it using while or for loops ?

Answer 1

You could test the condition using

if (op != 'A') {
    #Code1
    #Code2
    #Don't execute this part for op == 'A' 
}

#Code3
#Code4
#Execute this part for everything
