Hi, 
I am searching for the equivalent of the function Index from SAS. 

In SAS: index("abcd", "bcd") will return 2 because bcd is located in the 2nd cell of the abcd string. 
The equivalent in R should do this:
> myIndex <- foo("abcd", "bcd") #return 2. 
What is the function that I am looking for?

I want to use the return value in substr, like I do in SAS.

thanks, y. baranan.
