R:
if (condition) xxx else yyy
if (condition) xxx else if (yyy) zzz else qqq
C:
condition ? xxx : yyy;
condition ? xxx : yyy ? zzz : qqq;
If this is a beauty contest, or a readability contest, I'll take R!
?: is pleasant in C because it avoids so much of the C syntactic
sugar, of which R is largely free.
As for ifelse(), for a trivial example, try running:
ifelse(array(rep(c(1,0), 50), dim=c(10,10)), "00", "99")

if (!condition) stop("the condition", condition, "has failed")
if (condition) cat("my condition", condition, "is met")
