first thing to do when trying to speed up a function is to see where it is
spending its time. take a subset of the data and use Rprof to profile the
code. my guess is that a lot of time is taken up in the use of dataframes.
see if you can use matrices instead.

Hi,
I have written a function to assign the values of a certain variable 'wd' from
a dataset to another dataset. Both contain data from the same time period but
differ in the length of their time intervals: 'GPS' has regular 10-minute
intervals whereas 'xact' has irregular intervals. I attached
