Hello, I'm reading this and one part is confusing me (the most ;-) library(dotwhisker) library(broom) library(dplyr) m1 <- lm(mpg ~ wt + cyl + disp + gear, data = mtcars) # Please compare: dwplot(m1) dwplot(tidy(m1)) Why is the dwplot of tidy(m1) so different from the dwplot of m1? I had thought that tidy just gathers data from m1 and that that is what dwplot is showing, but the latter shows results that are closer to what you get from inspecting m1: Coefficients: (Intercept) wt cyl disp gear 43.539847 -3.792867 -1.784296 0.006944 -0.490445 Sorry if I'm being stupid, but the latter looks right while the former looks wrong (i.e. I can't work out what the former is actually plotting). Many thanks, Dan.
Question about dotwhisker

Sorry, forgot to link the actual vignette: https://cran.r-project.org/web/packages/dotwhisker/vignettes/dotwhisker-vignette.html In fact the vignette states: dwplot(m1_df) #same as dwplot(m1) where m1_df is m1_df <- tidy(m1) They are not the same in either the vignette itself or on my computer. I don't understand the part about "rescale the coefficients", but it seems that that is now the default... Just visually at least... If the plots in the vignette are auto-generated from code, then that would explain why the discrepancy isn't mentioned in the text.
