geom_pointrangeh()-equivalent without ggstance?

[Yuki Takahashi]

Dear all,

The ggstance says that ggplot2 version 3.3.0 (and above) now has horizontality support (https://github.com/lionel-/ggstance). What code would allow me to have a geom_pointrangeh()-equivalent graph?

MWE (borrowed from ggeasy question: https://github.com/jonocarroll/ggeasy/issues/20):

library(tidyverse)

library(ggstance)

# create example data frame

df <- data.frame(x = 1:100,

                 group = c(rep(TRUE, 50), rep(FALSE, 50)),

                 v = seq(-4, 4, length.out = 100)) %>%

    mutate(y = tanh(v),

           lower = tanh(v) - 0.2,

           upper = tanh(v) + 0.2)

# the legend key's lines are vertical

ggplot(df, aes(x, y, colour = group)) + geom_pointrange(aes(ymin = lower, ymax = upper)) + coord_flip()

# the legend key's lines are horizontal, but this uses ggstance. How to obtain this graph without using ggstance?

ggplot(df, aes(y, x, colour = group)) + ggstance::geom_pointrangeh(aes(xmin = lower, xmax = upper))

Best,

Yuki

I don't know a way to do what you want (adjust orientation of lines
in the legend) without ggstance. This works without coord_flip:

ggplot(df, aes(y, x, colour = group)) + geom_pointrange(aes(xmin =
lower, xmax = upper))

Another thing I haven't managed to do without ggstance is vertical
dodging (i.e., ggstance::position_dodgev)

This is discussed here:
https://github.com/tidyverse/ggplot2/issues/1389

and here: https://github.com/jonocarroll/ggeasy/issues/20

Thank you Ben. No, I either don't know why ggstance page says "This package has been superseded by ggplot2 3.3.0, which now has full native support for horizontality."

Best,
Yuki
