We have a small lab study in which each run is represented by a row in a tab-delimited file; each row identifies a repetition of the experiment and associates it with some subjective measurements and times from our notes that get used to index another file with lots of automatically collected data.  In short, nothing shocking.

The results were goofy, and the problem was in my code that runs before R ever sees the data.  That code was confused by things that I would like to ensure don't happen again, and I suspect that some of you might have thoughts on it.

If it insists on thinking for me, I wish it would think in 24 hour time and 4 digit years :)  I work on Linux, so Excel is off the table, but another spreadsheet or text editor would be a viable option, as would configuration changes to Calc.

No idea about Calc, I use it regularly but only to view files (and
that mostly csv, not tab-delinited). The most primitive solution is to
use a plain text editor such as vi that will save everything as it
loaded it except for what you change. The second most primitive idea
(or maybe not so primitive after all) is to read the table into R and
manually fix it there such as table$column[row] = "ABCD" (this is my
favorite way of changing things :)). The third most primitive idea
which I have actually never used but which may be viable is to load it
into R and use the fix() function that pulls up a rather primitive but
functional data editor.
