guide_stringlegend() throws Error in get_layer_key(...) : argument "data" is missing, no default

[adcascone]

I tried recreating the second set of plots using the code provided in the "String legends" section of the "Miscellanous" vignette, but guide_stringlegend() throws the following error: Error in get_layer_key(...) : argument "data" is missing, no default

Here is the code I tried:

p <- ggplot(mpg, aes(displ, hwy)) + geom_point(aes(colour = class))
p + guides(colour = guide_stringlegend(face = "bold", spacing = 15))

I see that the function's lifecycle is marked as 'questioning' on the function reference site - are there plans to update this function in future package versions?

Thank you!

Hi thanks for inquiring!

It seems to be working fine on my end, using ggplot2 3.5.1 and ggh4x 0.2.8.
What version combination of ggplot2 and ggh4x are you using?

are there plans to update this function in future package versions?

No I'm in the process of writing a separate package (gguidance) for guide extensions, where this one will be transferred to.

Thanks for the reply - I'm using ggplot2 3.5.1 and ggh4x 0.2.6

And good to know about transferring this function to the new package - I appreciate the insight!

I'd recommend updating to 0.2.8, there were some breaking changes in ggplot2 that required some adaptation in ggh4x.

I'm going to go ahead and assume that updating has fixed the issue. I'll reopen if somebody points out I was mistaken.
