I have exported a list of 2d coordinates as a `List`: Export["F:\\coordinates.dat", coordinates, "List"]; You can access the data here: http://pastebin.com/wFSt9DiD Now I would like to read the coordinates back with: coordinates = Import["F:\\coordinates.dat", "List"]; So far this works. But, when I want to plot the data with `ListPlot` the plot is empty. When I try `Flatten[coordinates]`, the coordinates remains unchanged. It seems that the imported data is imported as a text list. How can I access the data in the list?
