Error in plot.window(...) : need finite 'xlim' values
 In addition: Warning messages:
 1: In xy.coords(x, y, xlabel, ylabel, log) : NAs introduced by coercion
 2: In xy.coords(x, y, xlabel, ylabel, log) : NAs introduced by coercion
 3: In min(x) : no non-missing arguments to min; returning Inf
 4: In max(x) : no non-missing arguments to max; returning -Inf
 5: In min(x) : no non-missing arguments to min; returning Inf
 6: In max(x) : no non-missing arguments to max; returning -Inf

The problem is that the code is assigning the character strings "V1" and "V2" to x and y, and not the numerical data. It is needed to assign the read.table results to a variable.
