R help - Jul 2011 - deming regresion to make 2 variables comparable

Hi,

I have a dataset which has var1 from 1 sourse and var2 from 2 different
methods. I need a new variable such that var2 values from both methods can
beused as 1 variable.
I believe deming regression can be used to do this. I just don't know how to
do it.

My data looks like:
idvar1var2method1var2method2
11.22.1NA
21.62.4NA
31.52.2NA
41.3NA2.8
51.6NA3.1
61.4NA2.7


Please help.

Sincerely,
Devon

See if the following thread

and the paper cited in it are helpful. Terry Therneau provides code
for a Deming regression.
