[R] renaming intercept column when retrieving coeficients from lme using coef function

[jim holtman]

Is this what you want:

> coef.y
  (Intercept)
1  0.03109602
2  0.03109602
3  0.03109603
4  0.03109602
> str(coef.y)
Classes ‘coef.lme’, ‘ranef.lme’ and 'data.frame':       4 obs. of  1 variable:
 $ (Intercept): num  0.0311 0.0311 0.0311 0.0311
 - attr(*, "level")= int 1
 - attr(*, "label")= chr "Coefficients"
 - attr(*, "effectNames")= chr "(Intercept)"
 - attr(*, "standardized")= logi FALSE
 - attr(*, "grpNames")= chr "ID"
> names(coef.y) <- 'myName'
> coef.y
      myName
1 0.03109602
2 0.03109602
3 0.03109603
4 0.03109602
