tip_length in aes

[stanstrup]

Would it be possible to set the tip_length in the aes?

I am working on some time series data. So making a custom dataframe with the annotations could be nice.
Since I am comparing two different time series at same time/x it would be nicer to remove the tip and just have the p-value/annotation.

Here is an example (not time series though, just as an example for this specific problem):

annotation_df <- data.frame(color=c("E", "H"), 
                            start=c("Good", "Good"), 
                            end=c("Very Good", "Good"),
                            y=c(max(diamonds$carat), max(diamonds$carat)),
                            label=c("Comp. 1", "Comp. 2"),
                            tip_length = c(0.5,0))

annotation_df
#>   color start       end   y   label
#> 1     E  Good Very Good 3.6 Comp. 1
#> 2     H  Fair      Good 4.7 Comp. 2

ggplot(diamonds, aes(x=cut, y=carat)) +
  geom_boxplot() +
  geom_signif(data=annotation_df,
              aes(xmin=start, xmax=end, annotations=label, y_position=y, tip_length = tip_length),
              textsize = 3, vjust = -0.2,
              manual=TRUE) +
  facet_wrap(~ color) +
  ylim(NA, 5.3)

Hey, thanks for the suggestion.

I have implemented the feature and it is available when you install from github:
devtools::install_github("const-ae/ggsignif")

  annotation_df <- data.frame(color=c("E", "H"),
                              start=c("Good", "Good"),
                              end=c("Very Good", "Good"),
                              y=c(max(diamonds$carat), max(diamonds$carat)),
                              label=c("Comp. 1", "Comp. 2"),
                              tip_length = c(0.2,0))

  annotation_df

  ggplot(diamonds, aes(x=cut, y=carat)) +
    geom_boxplot() +
    geom_signif(data=annotation_df,
                aes(xmin=start, xmax=end, annotations=label, y_position=y, tip_length = tip_length),
                textsize = 3, vjust = -0.2,
                manual=TRUE) +
    facet_wrap(~ color) +
    ylim(NA, 5.3)

Thanks!

This still leaves a small dot. Any way to get rid of that?

[const-ae]

Oh you are right...
I will see if I find a good solution, but I can't promise a quick solution, as I won't have time next week.

It's strange:
If I run the code interactively, I don't see the dot.
If I create a reprex in new R session, it reappears.
