Never mind, I think i figured:
z<-df
apply(df,1,function(x) approx(sort(x[1:4]), seq(0,1,,length(x[1:4])), x[5])$y)
thanks again for the help

Peter,
thanks, very nice, this will work for me... could you also help with setting up the code to run the on liner "approx(sort(x), seq(0,1,,length(x)), q)$y" on the rows of a data frame using my example above? So if I cbind z and res,
df<-cbind(z,res)
the "x" in your one liner would be the first 4 column values of each row and "q" is the last (5fth) column value of each row..
thanks again for all the help,
Andras Farkas
