I am running an expt that presents a point process input x and
measures a point process output y. The times of each event are
recorded. The lengths of the data records of x and y are necessarily
different, and can be different by a factor of 10. I would like to
save these data after each experiment as a file with two columns, one
for x and one for y.
However, R dataframes require columns of equal length. One solution is
to fill the "empty" places in y with NAs so it has the same length as
x. I view that as unsatisfactory (there are in reality no missing
values). Another possibility is to store x and y in separate files. I
also view that as unsatisfactory (it is too easy to lose track of the
y file corresponding to a given x file).
Can anyone suggest a way to deal with this situation?
Hi Bill,
xy<-list(x=1:10,y=1:100)
Note that this cheerfully ignores how you are going to figure out which
x goes with which y(s).
