If appropriate for your data, you could try errors-in-variables (package leiv)
or use the first component from principal components.

Subject: [R] "regression" line of 2 independent variables

Hi, I would like to a draw a scatterplot of x1 and x2 (plot (x1, x2)), and also
want to draw a sort of "regression" line across the data points. But x1 and x2
are just 2 independent variables, so in this case a regression of x1 over x2, or
vice versa, is not appropriate per se. What would be an appropriate way to do
this? Thanks for any suggestions.

John
