This vignette shows how to use the viewAHPtree() function to build a hierarchical AHP structure from an Excel file. The example file is bundled with the package.
We assume the AHP structure is in the “ahp” sheet.
AHPstruc <- read_excel(file, sheet = "ahp")
print(AHPstruc, n=Inf)

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
