Printing only even numbers in a loop

[WisamAlkheder]

Hi everyone,

I'm having trouble figuring out how to only print the even numbers in a for loop seq.

I was able to do this:

`> for(i in seq(1:10)){

• print(i%%2)} [1] 1 [1] 0 [1] 1 [1] 0 [1] 1 [1] 0 [1] 1 [1] 0 [1] 1 [1] 0`

And I can produce an answer whether the number is even or odd (true or false).

How do I limit the printing to the even numbers though? without having to show the rest of the numbers (or zeros).

Best, Wisam

You can use an if statement to check if the number is even, and write a print command in the body of that if function.That would print only the even numbers. Also , when you write " i %%2 " you just calculate the mod value(remainder) when "i" is divided by 2, you also need to check if thats equal to 0 to make sure "i" is even

Thanks Mohanpreet. If this is still not clear come to class tomorrow and we can go through it.
