This sample data is provided to show how dose-response data can be collected with a spreadsheet program like OpenOfficeCalc (sampledata.ods) or MS Excel (sampledata.xls) and exported to CSV (comma separated values) format. OpenOfficeCalc 2.0 (German version, decimal separator is ',') produces sampledata.csv which can be read in by >sampledata <- read.csv('sampledata.csv',skip=2,dec=',') and MS Excel 97 produces sampledata.csv2 which can be read in by >sampledata <- read.csv2('sampledata2.csv',skip=2) if the working directory of R was set to the directory where these files reside.
