read.table with double precision

I'm having trouble replicating/understanding why that would happen since I do it all the time. The only thing that raises a hint of suspicion is using the blank space separator , but I'm pretty sure that's fine What does str() give? Possibly factors? If you are sure that's happening as described, can you send a sample .txt ( won't get scrubbed) and your exact import code? Michael

Using that exact file you included? If so, then I suspect you are confusing display and storage, though even then my default session doesn't show integers. How do you know that it is returning only integers? What is options()$digits set to?
myfile
V1 V2 V3 1 1 50.790643 6.063498 2 2 50.790738 6.063471 3 3 50.791081 6.063380 4 4 50.791189 6.063552
sprintf("%2.10f", myfile[1,2])
[1] "50.7906430000"
What can I do to force it to store things into doubles?
What is str(myfile) ? Sarah
