[R] Getting rate of return

[Salvatore Barbaro]

# Hi,

# define as r the revenue and as c the cost
# for example:
r<- 60
c<- 50
# function to obtain the rate of return:
ror<- function(r,c){
foo<- r/c-1
return(foo)
}
# the command ror(r,c) gives you the required rate of return
ror(r,c)

best regards

s.

Dear R help.
I have a beginner's question to ask you. I faced a difficulty in
getting rate of return for some target data. I finished data importing
and some manipulations. but I have any idea after that. Anyone 
who
answer this question?

Thanks in advance
