I believe the R intro manual and R-inferno have some pretty stern
warnings about never using 'c' or 't' as variable names, for obvious
reasons.
Similarly, I nearly crushed some code once by writing a nice little
function to find the mode of a data set and calling the function
mode() .

I think both responses so far have missed the point, (assuming the O was a typo
for zero).
That is:
seq(0:1)
[1] 1 2
when
seq(0,1)
[1] 0 1
was intended.

Clearly my own brain to fingers fumble, but possibly one others may want to
avoid it.

So you are warning us that you must type zero instead of the letter O
when we want to enter the value of zero? Seems pretty obvious...
