I have a very large data set stored as an xts object.
xts is very nice about showing row labels as human readable dates and times.

This is one of those cases where following the posting guide

In the current version (2.13.1) textConnection is much slower if you have a
large file (1 lines) than using a temporary output file. Try timing a
script using the two different approachs to get an appreciation for the
