It means that 'write' is the name of a variable in the dataset. R is
warning you that you have two things called 'write' -- your variable and a
function in the base package.
It also means that you have missed at least three upgrades of R (the
fourth is just out) since in version 2.3.0 and more recent you don't get
the warning when a variable and a function have the same name, only for
two variables or two functions. There have been quite a lot of other
changes since your version of R, so it would be worth upgrading.
