Can we have an if loop inside a for loop in R programming

Question

I'm using R programming and this code is giving error:

for(i in 1:length(abc)){
  print(i)
  if(){}
}

Any help would be appreciated

Answer 1

You're If loop doesn't have any condition and Empty conditions result in an error:

> if(){}
Error: unexpected ')' in "if()"

Use TRUE or FALSE if you want to run the loop.
