Hi Petr, polygon doesn't work very well, because I need a graphical display for the laboratory results of my institute. So I have a lot of data in .csv-format, and I don't really want to define a new polygon for each dataset, because then I have to do a lot of extra-work. I need a solution that works like the following, but with coloring the area under the function (like the image in my first posting):
labdata <- read.csv("labdata.csv", header=TRUE) attach(labdata) #for using column-names as variables plot(variable1,variable2,type="s",main="Title",ylim=c(120,0),xlim=c(0,10)) For each .csv-dataset I want to use this code with only slight adjustments...
