Hi Bill,
This seems a bit like some heartbeat data that I had to deal with some 
years ago. There were two output streams, one the time of each R wave 
and the other an asynchronous stimulus. In that case, I had to work out 
code to interdigitate the signals and do some processing of the 
resulting data. It sounds like you have two files, each recording times 
of input and output respectively one value to a line. If so, my first 
guess is:

x<-as.vector(read.table("input_times.dat"))
y<-as.vector(read.table("output_times.dat"))
xy<-list(x,y)
# to store this list in a file
write.csv(xy,file="xy_23_10_2009.csv")
