Dear list, this seemed to me like a very trivial question, but finally I haven't found any similar postings with suitable solutions on the net ... Basically, instead of regressing two simple series of measures 'a' and 'b' (like b ~ a), I would like to use independent replicate measurements for eac

Hello, Though Bert's and David's answers are what you should do, note that some R functions that need factors will coerce their input variables when necessary. Have you tried to run the code you haven't posted without coercing to factor? It might run... Hope this helps, Rui Barradas On 4/9

Have you ever noticed that when you run x <- 1:5 y <- 2:6 plot( x, y+1 ) you get the expressions you used in your call to plot on the axis labels? `x` is an expression consisting of a single symbol and y+1 is an expression consisting of the addition operator and two arguments: the symbol x and
