R help - Nov 2013 - Functional Programming patterns

Hi,
' 
Not specific to 'R'. I search for patterns and found 
http://patternsinfp.wordpress.com/ which is too heavy for me. There is a 
'Pragmatic Programmer' book on such patterns for Scala and Clojure. Is 
there anything for R ?

I wanted to code this. Is there a functional pattern in R for multiple 
'if' loops like this ?

        if( is.na(str_extract(input,"T[^.]*")[1]) ){
 
        }else{
 

Thanks,
Mohan

Have you checked the r.lambda package of Brian Lee Yung Rowe
?

I have some notes on functional programming in R at http://adv-r.had.co.nz/.
