[R] Combining Data Frames

I have two dataframes in R that were tab seperated .txt files

y<-read.table("foo.txt", header=T)
x<-read.table("foo.txt", header=T)

these are set up like this:

Datetime                 Temp
01/01/07 00:01         11.5
01/01/07 00:16         11.6

etc etc to 66000 rows in y and 33000 rows in x

The two files overlap with the same data for a period of time but contain different values outside of these. Is there a way to merge these two data sets based on the shared date time column into one large dataset of ~90,000 lines. I want to eventually make this into a time series with frequency= 1/15.



Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
