Hallo, can someone please help me. I have a proplem reading a file with more that one rows. e.g I used the function: p<-read.table(file="FILENAME ", header=TRUE,sep=";") and later used the data.Frame() function. It functions when the file has only a row of variables. When I insert the second row I get an error message. How do I do this ===== ===================== Sylvie

Regression tree
Hi everybody. I'm a new R user and i've been searching a tool for construction of regression tree... I found function "tree()" written by a certain Mr. Ripley, and seems to be just what i'm looking for, but when i try to use it in R replies me:"Object not found". So I was wandering if I should include one special library or something like that? Thanks a lot, ana

Program Saving

Basic question on applying a function to each row of a dataframe
Hi, I have a function foo(x,y) and a dataframe, DF, comprised of two vectors, x & w, as follows : x w 1 1 1 2 2 1 3 3 1 4 4 1 etc I would like to apply the function foo to each 'pair' within DF e.g foo(1,1), foo(2,1), foo(3,1) etc I have tried >apply(DF,foo) >apply(DF[,],foo) >apply(DF[DF$x,DF$w],foo) However, none of the above worked. Can anyone help ?
