Force R to print 0/0 as 1

When I execute 0 / 0 in R, I would get a NaN as an output. But is there any way I could print 0 / 0 as 1? I know I could use some if statements to achieve it. I would like to know if there is any other way to achieve this.

You could define your own division symbol especially for this. For example,

'|' <- function(a,b)ifelse(a==0 & b==0, 1, a/b)

> 0|0
[1] 1
> 3|4
[1] 0.75

Other way than using If statement would be

# Assign NaN to vector
a <- 0 / 0
# If is NaN assign value 1
a[is.nan(a)] <- 1
