Why not use the x=T and y=T paramemters and see if :
linearmodel=lm(y~x, x=T, y=T)linearmodel$model
(linearmodel$model)
y x
1 2 1
2 4 2
3 6 3
4 8 4
5 10 5
give you useful results. If you want to interpolate or
extrapolate, then search for threads regarding those tasks.

Dear List,
Consider the following example
x=c(1,2,3,4,5)
y=c(2,4,6,8,10)
linearmodel=lm(y~x)
To predict a y-value if you know the corresponding x value is very easy
with the command predict.
predict(linearmodel, newdata=(x=1.5))
The other way around, to predict an x-value with a correspondin
