[R] Orthogonal Distance Regressions

[Peter J. Hernes]

Hi,

I work with environmental data and want to determine correlations between 
variables that either have no "dependent/independent" relationship or the 
relationship is unknown.  Therefore I prefer to use orthogonal distance 
regression (orthogonal linear regression, perpendicular sum of squares, 
etc.).  I am trying to get set up to do this in R, but the various 
terminologies are making it challenging for me to determine whether this 
capability exists in the base packages (it doesn't look like it to me) or 
which other package I should download to do this.  Searching the R website 
for any of the three terminologies above has not given me any obvious 
solutions.  I would appreciate any assistance from folks with experience 
doing this type of regression.  Thanks in advance!

Peter
