Re: How to read a data file in text format?_from a new learner

my pattern for reading files like these would be:

 thisFile = OpenRead["C:\\Documents and Settings\\Luc\\Desktop\\sample.txt"];
 data = ReadList[thisFile, String];
 Close[thisFile];

Then you need to remove the first line:
 data2 = Rest[data];

Then transform the strings into proper numbers:

 data3 = ToExpression[StringReplace[#, {"," -> "", " " -> ""}]] & /@ data2

Finally plot the data:

 ListPlot[data3, PlotRange -> All]
