R programming: leap years calculation

0 votes

I'm creating a function that returns leap years. However, my code returns the results in the form of logical vector. How can I get the results in numeric vector. For example, for the below code the result should be "c(2000,2004,2008)"

    "ans<- function(year1, year2)
 {return(((c(year1:year2) %% 4 == 0) & (c(year1:year2) %% 100 != 0)) | (c(year1:year2) %% 400 == 0)); return(c(year1:year2))}"

 ans(2000,2010)

TRUE FALSE FALSE FALSE TRUE FALSE FALSE FALSE TRUE FALSE FALSE

Here's a small modification to your code, try this, it should work:

ans<- function(year1, year2){
  return(c(year1:year2)[((c(year1:year2) %% 4 == 0) & (c(year1:year2) %% 100 != 0)) | (c(year1:year2) %% 400 == 0)])}

> ans(2000, 2010)
[1] 2000 2004 2008
