Had you not been aware of the seq function, as mentioned by others,  
you could also have used:

for (i in 1:100/10) {
             hey[i] <-  diddle(dee[i])
                     }

Because ":" has higher precedence, you would not need to enclose the  
sequence in parens. This precedence rule is sometimes the source of  
confusion and I believe there is a FAQ item based on that source of  
confusion.
