[R] Merge the data from multiple text files

[Priya Arasu]

I have multiple text files, where each file has Boolean rules.
Example of my text file 1 and 2
Text file 1:
A = not(B or C)
B = A and C
C = D
Text file 2:
A = D and E
B = not(D)

I want to merge the contents in text file as follows
A = not(B or C) and (D and E)
B = not(D) and (A and C)
C = D
Is there a code in R to merge the data from multiple text files?
Thank you
Priya
