I have two text files that are measure the X and Y coordinates of cells. The command "dim(file.txt)" returns "NULL" for each of the files. One of the files contains lines of X coordinates (xline1.1, x line1.2, x line1.3) followed below by a second line of coordinates for a separate entity (x line2.1, x line2.2, x line2.3) 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.

I am inexperienced but my plan so far, is to use the "lapply" function to apply "create.file() and "file.path()" to each consecutive line of the X and Y files such that a new file will be created for each line. I plan to use "merge()" to merge all of the newly created X files with the corresponding Y files some how....

Any critiques are welcome.

I'd suggest trying your code and when you run into problems, you can post some example files and the code you are using.  I'm not at all clear what you are proposing to do without seeing the code.

I still doubt that this is bioinformatics. Also, your question is posed in a way it is impossible to comprehend, because you are mixing input and output in your example, further it is irrelevant that dim(file.txt) is NULL, because dim works on datastructures not on files. If you specify the conversion you should do it in a way where the same objects have the same names, in your example there is not a single symbol appearing twice.

Also, you shouldn't speculate on how to solve the problem, before it is defined properly.

Mike, I have already tried to answer his question in an almost exact same post.  trying to put values of two dimensionless files side by side

Could you close this post as well? I think this question is irrelevant to Bioinformatics as well.
