operator problem within function
...ames within a function using the "$".
Here´s my code:
recode_items = function(dataframe,number,medium=2){
# this works
q<-paste("columna",number,sep="")
# this does not work, particularly because "dataframe" is not processed
# dataframe should be: givenframe$columnagivennumber
a=dataframe$q[dataframe$q==medium]=1
return(a)
}
If I call this function, i´d like it to return my dataframe. The problem appears to be somewhere around the $. I´m sure this not too hard, but somehow i am stuck. I´ll keep searchin the manuals.
Thx for any help in adv...
