[R] p-value for the fitted parameters in linear models

[Li SUN]

Sorry for the confusion.

Let me state the question again. I missed something in my original statement.

When using the linear model lm() to fit data of the form y = k * x +
b, where k, b are the coefficients to be found, and x is the variable
and has an error bar (uncertainty) Δx of the same length associated
with it. Is it possible to pass Δx to the linear model lm(), and from
the output to find the uncertainty Δk for k, Δb for b as well?
