Dear smart ones,
Image a vector 'test' that looks like so:
0
0.5
1.5
2.1
3.1
4
I'm looking for an efficient function that would do something like
moddown <- function(test,integer){
for (element %in% test){
if (element%%integer != 0) {
"return next lowest integer for which '%%' returns 0"
} else {
"return element"
}
}
}
and return for 'test' a vector like so:
0
0
0
2
2
4
My current solution like outlined above seems very inelegant ...
Thanks for any hints, Joh
