Look at the last example in the recode help page:
recode(x, "1:2='A'; 3='B'")
## [1] "A" "A" "B" "A" "A" "B" "A" "A" "B"
It appears to me that the c() function around your sequences may be  
part of the problem and I further wondered whether 0:49.99 can  
succeed. Generally the ":" operator expects integer arguments, but the  
help page is not clear in this area and it appears that recode has a  
different interpretation.
