You can always read in the initialization file, make the updates to it and then write it back out. If it is a text file, it would be very hard to write into the middle of it since there is no structure to the file. You can read it in as a table (read.table) or just as lines (readLines) and the make any changes you want. You can use regular expressions if you want to put something in the middle of one of the lines you have read in.
