columns from the file. I have Excel sheet, of course can save into any
readable format. Appreciate your help.
Thanks.

save it as .csv, then use read.csv("your_file.csv")

Hi Jim,
Saving is not a problem. I wanted to load/read the columns from the
file followed by plotting the area plot using ggplot2.
I am a basic user. I am trying to reproduce the plot similar to the example
given here.

Hi Kishore, There should be no problem reading in your data if you have followed the directions posted by Jim and myself. I suggest you do a search for a basic R tutorial and follow that through.
