Alpha error about ggsignif

[shellyc26]

Actually, I just realized that it was because I had the "psych" package loaded. It works once I detach the psych package!

Is there any way to get around this, though? I almost always use this package, and having to detach it every time I plot is a bit irritating. Any ideas?

Hey, thanks for raising the issue.

You are right when the psych packages is loaded, it loads a new alpha() function. Internally I was calling alpha(), but forgot to specify that I want the scales::alpha() and not just which ever was loaded last.

I fixed the issue and you should now, after reinstalling the package from github, be able to use package without problems:

devtools::install_github("Artjom-Metro/ggsignif")

I will try to update the CRAN version as soon as possible so other users are not affected as well.

Awesome, thank you! This is a fantastic idea for a package!

I have another question (and can put it in a separate thread if you'd like). Is there any way to make the horizontal line/line tips a different linetype? For example, if I wanted a dashed horizontal line? I kept trying to pass the linetype = 2 to various plot layers (including the base layer), but that didn't work. Other aesthetics like color (changes color of both the line and the annotation) and size (changes size of annotation only) worked just fine. Any suggestions?

I think having the option for dashed lines might be useful, especially for making figures for publications that require black and white images (or those that make you pay for color images). Thanks again!

Great, that it worked for you.

The second point you raise sounds also like something that should reasonably work, but please open a new issue so this stuff is kept separated.
