[R] Model II regression

[JEAN-LOUIS HEMPTINNE]

Hello,
I am using function lmodel2 to calculate RMA regression between
life-history traits in ladybirds beetles. It works well but I am not able
to plot an RMA regression line on the scatterplot of my data. I am of
course unable to plot the confidence intervals. For ordinary least square
regression abline(lm(x~y))works well but for RMA regression,
abline(lmodel2(x~y))does not do it. 
If somebody knows how to do it, it would be a great relief !!
Best wishes,
JL
