I tested your data and commands without any error message on
a linux debian distribution:
> z<-lda(assignment ~ .,actaData,prior=prio,tol=1.0e-08)
lda.formula(assignment ~ ., data = actaData, prior = prio,
tol = 1e-08)

You can upgrade your old R while keeping the system in
stable. You may download the 1.7.1 deb packages from CRAN,
and install them with dpkg.
Or even better, you can create your own debs from the
sources, all the required files are the package.
tar xvzf R-1.7.1.tgz
And a few coffees later, you will find a fairly large number
of deb files in the parent directory.
