Hi I am following along (using my own data) the processes described by  "glmulti: An R Package for Easy Automated Model Selection with ( Generalized ) Linear Models"
Journal of Statistical Software
May 2010, Volume 34, Issue 12. http://www.jstatsoft.org/

I will send the pdf if requested, however, I doubt it will get though attached here.

I am having trouble understanding why I am getting these warnings:

ga1 <- glmulti(y ~ a+b+c+d, fitfunc = glm, crit = aic, method = "h")

plot(ga1, type = "p", highlight = c("d:a","d:b"))
Warning messages:
1: In plot.window(...) : "highlight" is not a graphical parameter
2: In plot.xy(xy, type, ...) : "highlight" is not a graphical parameter
3: In axis(side = side, at = at, labels = labels, ...) :
  "highlight.3d" is not a graphical parameter
4: In axis(side = side, at = at, labels = labels, ...) :
  "highlight.3d" is not a graphical parameter
5: In box(...) : "highlight" is not a graphical parameter
6: In title(...) : "highlight" is not a graphical parameter

The authors describe the plots on pg. 15

Also I am not getting the highlights in my plots as is shown in the author's document?

I suppose I could reach out to the authors, assuming 8 years later the e-mail address is the same, however before I did that I thought maybe someone out here might know why this is happening for me.

Here is my structure

y <- r1$Editnumber2
a <- r1$productID
b <- r1$ProviderID
c <- r1$SavingsReversed
d <- r1$PatientGender

ga1 <- glmulti(y ~ a+b+c+d, fitfunc = glm, crit = aic, method = "h")


I have looked at https://cran.r-project.org/web/packages/scatterplot3d/scatterplot3d.pdf for more info on highlight and it refers to highlight.3d which I also tried, no difference.

Thank you for any insight.
