[R] Simple question, I think

[David Kaplan]

Greetings,

I am recoding a dummy variable (coded 1,0) so that 0 = 2.  I am using 
the line

sciach$dummyba[sciach$ba==0] <- 2

I notice that it creates a new column dummyba, with 0 coded as 2 but 
with 1's now coded as NA.  Is there a simple way around this in the line 
I am using, or do I need to have an additional line

sciach$dummyba[sciach$ba==1] <- 1

Thanks in advance.


David
