No. You should either create a set of dummy data of a similar size that 
reproduces the problem, or post the data set on a web site:

ge = read.table("http://www.menne-biomed.de/gastempt/gastempt.csv",
  sep=",",header=TRUE)

And the code should be complete so that someone can run it with copy/paste.
