See the Dobson example in the lm documentation. Assuming your x-values are known
accurately enough, you could use your y-variances as weights; this could be a
good approximation to what you want.
If that's not enough, check one of the packages with "meta" in it.
You may
get better responses when you provide a self-running example as the posting
guide says.
