To whom it may concern, I am a new user to R and I need help in my if and for statements as I need a place marker.
I would like to convert the following table: Observation | Variable 1 --------------------|------------- 1 | 10000 2 | A 3 | 631 Into : Observation| Variable 1 | Variable 1 Flag ----------------|------------------|------------------ 1 | 10000 | NA 2 | NA | A 3 | 631 | NA please note | represents another column. this is for a large data set and I cannot manually go through this: my attempt to this was : l=0 # placeholder m<-c() #newvariable 1 v<-c() #newvariable flag for (z in tablename1$Variable_1) (if (is.numeric(z) ) m[z:l] l=l+1 else v[z:1] l=l+1 Can you please guide me as to how to approach this problem? Any help would be greatly appreciated.
