operator problem within function
...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 advance. best matt [...
