Changing the x.label in Johnson Neyman plot using sim_slopes

Hi there,

Firstly, thank you very much for such a helpful package.

I was wondering whether there is a way to change the x axis label in a Johnson Neyman plot using sim_slopes? When I use the following code, a JN plot is generated, but the x axis label is still the name of the moderator variable from my dataset, rather than what I have specified as a relabel:

E.g. The following example code generate JN plots, but without label changes:

sim_slopes(ModelA, pred = predictorA, modx = modA, johnson_neyman = TRUE, modx.labels= "Moderator A", jnplot = TRUE)

OR

sim_slopes(ModelA, pred = predictorA, modx = modA, johnson_neyman = TRUE, x.label= "Moderator A", jnplot = TRUE)

Thank you!

Start by tracing sim_slopes with johnson_neyman and jnplot enabled, then inspect how modx.labels and x.label are handled for the Johnson-Neyman plot. Confirm the change when the plot uses the requested x-axis label while the provided example still generates the plot.
