How to handle "car.ahp" file?

[jjangkr]

I edited little bit on "car.ahp" file to test and rename it as "car2.ahp".
Then I tried to load it.

The error message for this is as below;

library(ahp)
ahpFile2 <- system.file("extdata", "car2.ahp", package="ahp")
carAhp2 <- LoadFile(ahpFile2)
Warning message:
In file(con, "r") :
file("") only supports open = "w+" and open = "w+b": using the former

How do I handle it?
Do I have to make "example.ahp" by using "yaml" type file?
Then how can I edit and save "yaml" file.
Text editor is not working.

I cannot reproduce that error. But in any case, I suggest not messing around with your libPaths. So, what I would do is:

1. copy the file car.ahp to a folder where you have adequate permissions, e.g. your home directory (on linux) or My Documents on Windows
2. edit the file in a text editor (e.g. nano, or Notepad++)
3. use LoadFile directly on the copied file, e.g. LoadFile("home/my_ahp_tests/car2.ahp")
