how to create time slot vector from two numeric vectors in R

Question

I have stored two vectors as

hrs <- sample(0:23,500,replace=T)
mins<- sample(0:59,500,replace=T)

so my question is can we store these two vectors in HH:MM format in single vector in R language?

Answer 1

We can use paste

paste(hrs, mins, sep=":")

If we need the HH:MM format, use sprintf

sprintf("%02d:%02d", hrs, mins)
