panel.lmbands()

[nicholasjhorton]

Is there an easy way to replicate the functionality of panel.lmbands() for ggformula plots? This is used several times in some of the mosaic materials.

xyplot(age ~ cesd, panel = panel.lmbands, data = HELPrct)

My proposal would be to include examples of how to create this functionality using broom::augment() and not craft a separate layer for this.

This exists already:

library(ggformula)
#> Loading required package: ggplot2
#> 
#> New to ggformula?  Try the tutorials: 
#>  learnr::run_tutorial("introduction", package = "ggformula")
#>  learnr::run_tutorial("refining", package = "ggformula")
library(mosaicData)
gf_point(length ~ width, data = KidsFeet) %>%
  gf_lm(interval = "confidence", fill = "red") %>%
  gf_lm(interval = "prediction", fill = "navy")

Created on 2018-06-15 by the reprex package (v0.2.0).

This looks great. Could it be added to the vignette? https://cran.r-project.org/web/packages/ggformula/vignettes/ggformula.html

I've added something. But I'm not sure the point of the vignette is to show every possible thing that can be done.

I've put this in the section on stats since these are using statistical transformations of the data.
