problem in substring()

[Nora Muda <noramuda@yahoo.com>]

Dear S-Plus users,

 

I have problems in using substring ( ) function. My question may looked simple to all of you, since I am new to Splus. I have problems to get back my 2 digits number after did paste ( ) function. 

 

Let say I have 10 numbers.

 

>y <- c(1:10)

>a <- as.numeric(paste(y[1],y[10],sep=""))

$a:

[1] 110

 

then I want to separate it back apart;

>as.numeric(substring(a,1,1))

[1] 1

>as.numeric(substring(a,2,2))

[1]  1    <------------   suppose I want '10' not '1'

 

I noticed that substring( ) separate one string at a time, how to do if we want 2 strings as my example above?

 

Hopefully someone will help to answer my questions.

 

Thank you in advance.

 

--Nora.
