Error message when implementing qqplotr

[JuanDiegoHL]

Dear Dr. Loy,

I hope you are well.

I recently found on the Internet the package you developed. I am trying to create a Q-Q chart with confidence bands, but when I recreate the example you provide (as it appears in https://cran.r-project.org/web/packages/qqplotr/vignettes/introduction.html), I get this error message:

set.seed(0)

smp <- data.frame(norm = rnorm(100))

gg <- ggplot(data = smp, mapping = aes(sample = norm)) +

• stat_qq_band() +
• stat_qq_line() +
• stat_qq_point() +
• labs(x = "Theoretical Quantiles", y = "Sample Quantiles")

gg

Error in stat_qq_band():
! Problem while converting geom to grob.
ℹ Error occurred in the 1st layer.
Caused by error in fill_alpha():
! could not find function "fill_alpha"
Run rlang::last_trace() to see where the error occurred.

Any help would be greatly appreciated. Thanks in advance.

Hi @JuanDiegoHL, what version of ggplot2 are you running? Have you tried updating it?

Thanks for your reply.

ggplot2 version 3.5.0 was released in February. Can you update and see if that solves the issue? I'm running 3.5.0 and can't replicate the error.

[JuanDiegoHL]

I already did that. It worked. Thanks a lot, Dr. Loy. Best regards.
