1. You should regress Elevation on Volume, no?
2. You are calling lm incorrectly for prediction. Please read ?lm and
related links carefully and/or consult a tutorial. R-Help is really not the
first place you should look for this sort of detailed info.
3. I think this is what you want:
lm1 <- lm
Dear all;
I have a dataframe with several columns. The columns are the elevation,
volume and the area of the cells (which were placed inside a polygon). I
have extracted them from DEM raster to calculate the volume under polygon
and the elevation for a specific volume of the reservoir.
