In R how do I find whether an integer is divisible by a number?

问题

Sorry for the inexperience, I'm a beginning coder in R For example: If I were to make a FOR loop by chance and I have a collection of integers 1 to 100 (1:100), what would be the proper format to ensure that would print the numbers that are divisible by another number. In this case, 5 being the number divisible. I hear that using modulo would help in this instance %%

This is what I think I should have.

For (x in 1:100) {
  x%%5 == y
}
print(y)

回答1:

for (x in 1:100) { 
  if (x%%5 == 0) {
    print(x)
  }
}

回答2:

How's this?

x <- 1:100
div_5 <- function(x) x[x %% 5 == 0]
div_5(x)

回答3:

for (i in 1:10) 
{
   if (i %% 2)
   {
      #some code
   }
}
