[R] extracting parts of words or extraxting letter to use in ifelse-func.

[joe1985]

Hello 

I want to make some variables with the ifelse-function, but i don't know how
to do it. 

I want to make these five variables; 

b2$PRRSvac <- ifelse(b2$status=='A' | b2$status=='Aa',1,0) 
b2$PRRSdk <- ifelse(b2$status=='B' | b2$status=='Bb',1,0) 
b2$sanVac <- ifelse(b2$status=='C' | b2$status=='sanAa',1,0) 
b2$sanDk <- ifelse(b2$status=='D'  | b2$status=='sanBb',1,0) 
b2$totalvac <- ifelse(b2$status=='San',1,0) 

And 

b2$UGT <- ifelse(b2$status=='UGT',1,0) 
b2$KOM <- ifelse(b2$status=='KOM',1,0) 

But, as one from this forum told me, it doesn't work because the words is in
a wrong format or something like that. 

I have attached the text-file i've used, and the R-kode. 

Hope anyone can help me?
