Load() is not reading pairwise

[xhan85]

I have made a yaml file and am trying to use the ahp package. I can use the yaml.load_file function but cannot use Load() because it returns that it cannot load the ahp model. I have found that it's running into problems with the pairwise comparison sections under preferences. When I use a bare bones version of my yaml file, it's able to be loaded. But once the pairwise comparisons are added back in, I keep getting the same error. It is having issues somewhere with parsing out the information in the pairwise comparison section. Thanks in advance!

My full yaml file is:

Your file doesn't seem to be indented correctly. I'm assuming this is a paste error.
Yes, error handling is very limited at this stage. Happy to look into it. Ideally you prepare a gist with the file and the code you run, so I can directly reproduce.

Thank you so much (sorry for the long delay on my side)! I have made a gist with both the yaml file and my R code. If you're able to tell me where I went wrong, it would be much appreciated! You can access the gist here: https://gist.github.com/xhan85/388d8e3e868a2663338bd1bd2883ee24

I had a quick look. Your file is in version 2, so you need to put Version: 2.0 in first line of the ahp spec yaml.

Also you can load directly on the file path.

gic <- Load("U:/EOA/AHP/GIC Assessment_wdoane.yml")
Calculate(gic)
Analyze(gic)

Using this, I get:
