Off topic:trying to put values of two dimensionless files side by side

Question

[chrisclarkson100]

I have two text files for which the command dim(file.txt) returns NULL. One of the files contains lines of X coordinates (x1.1, x1.2, x1.3) followed by a second line of coordinates for a separate entities (x2.1, x2.2, x2.3) the other contains corresponding Y coordinates and I'm trying to transform the files into separate the files to create a new file for each line such that the X and Y coordinates will line up side by side like so:

X1 Y1             AND      X2 from line 2, Y2 from line 2
x1.1 y1.1                      x2.1                 y2.1
x1.2 y1.2                      x2.2                 y2.2

etc.

Any tips?
