Warning: `fortify(<lm>)` was deprecated in ggplot2 3.6.0.

Tips for a helpful bug report:

I am using gglm and I got this warning:

gglm(linear.coyote, theme = theme_bw(base_size = 16))

Warning: fortify(<lm>) was deprecated in ggplot2 3.6.0.
ℹ Please use broom::augment(<lm>) instead.
ℹ The deprecated feature was likely used in the ggplot2 package.
Please report the issue at https://github.com/tidyverse/ggplot2/issues.
This warning is displayed once every 8 hours.
Call lifecycle::last_lifecycle_warnings() to see where this warning was generated.

The warning means that whatever package the gglm() function is from, ought to stop using lm-models as direct input for plots and opt for broom::augment() instead. Is the issue simply a request to elaborate on the warning?

thank you for your quick answer. I was just following the suggestion to report to you. The function gglm, comes from the package gglm. I get the sense of the warning. Thanks

Thanks for elobrating. The phrasing of the warning message is a bit unfortunate that it identifies ggplot2 instead of gglm of using the deprecated feature, but having knowledge of where fortify() is used I can see it would be difficult to redirect this part of the message to identify gglm. I've reported it in graysonwhite/gglm#7 and think we can let it rest for ggplot2's part in this.

Many thanks for your answer :-)
