Hi. What is "pres" and "sci.pre"? Probably, they are vectors of different lengths and they were interpreted as "x" and "y" in approx(), see ?approx. If "sci.pre" should be "xout" in approx(), then you have to specify some "y". The vectors "pre1" and "pre2" have lengths 12 and 20, but their relationshiop to "pres" and "sci.pre" is not clear.
