Where I have used;
b2$PRRSvac <- ifelse(b2$status=='PRRS-pos VAC' | b2$status=='Vac',1,0)
b2$PRRSdk <- ifelse(b2$status=='PRRS-pos DK' | b2$status=='DK',1,0)
b2$PRRSsanVac <- ifelse(b2$status=='sanVac',1,0)
b2$PRRSsanDk <- ifelse(b2$status=='sanDK',1,0)
to creat the last four variables, but it wont work!!! The variable status
has class "character".
Can anyone help me?
