Error in search_path_unsetup while running demo(unitizer)

[richierocks]

I ran

library(unitizer)
demo(unitizer)

and it worked OK until the line

unitize(.unitizer.test.file)

Then it failed with the following output

Search Path Setup...

I'm running R-devel 3.4.0 (rev 71184) under Windows 10 x64, in case it makes a difference.

Thanks for reporting. I have yet to test on R-devel, so that may be the issue. However, I have also made many many changes in the development branch, so I would really appreciate it if you could try:

devtools::install_github("brodieG/diffobj@development")    # need to add version dependency...
devtools::install_github("brodieG/unitizer@development")

and see if you get the same error.

Also, are you using Rstudio or just running Cli?

[brodieG]

Also, if you're currently on v0.9.0 of unitizer, you can try setting options(unitizer.search.path.clean=FALSE) to disable search path manipulation for the time being.

Using development versions of unitizer and diffobj, the demo ran fine for me under:

R Under development (unstable) (2016-09-11 r71233) -- "Unsuffered Consequences"

Platform: x86_64-pc-linux-gnu (64-bit)

[brodieG]

I pushed a new version out to master that should address this issue and many others (1,000 commits since the version you tried). The problem was caused by changes introduced in R-devel.

Also, obviously, @richierocks feel free to re-open if it is not fixed for you.
