pkg_ref() returns indefinite list for $version ?

[paulie-of-punskas]

When running pkg_ref() alone, an indefinite(?) nested list is created for version object:

On the other hand, if I call the object directly, it returns me a single list:

Code used for reproducing the issue:

# === load riskmetric library
library("riskmetric")
library("magrittr")

# === create testing environment
dir.create(paste0(tempdir(), "/test_riskmetric"))
dir.create(paste0(tempdir(), "/test_riskmetric/source"))
dir.create(paste0(tempdir(), "/test_riskmetric/library"))
dir.create(paste0(tempdir(), "/test_riskmetric/downloads"))

# === download and unpack files
pkgs <- c("askpass", "dplyr", "openssl")
download.packages(pkgs, destdir = paste0(tempdir(), "/test_riskmetric/downloads"))

lapply(list.files(paste0(tempdir(), "/test_riskmetric/downloads"), full.names = TRUE),
       untar, 
       exdir = paste0(tempdir(), "/test_riskmetric/source"))

# === get license
pkg_references <- lapply(pkgs, function(xx) { pkg_ref(x = paste0(tempdir(), "/test_riskmetric/source/", xx)) } )

This is a result of the package_version class, not {riskmetric}. At this point I'm not sure this causes any problems with the current workflows to analyze the risk of a package. I will keep this open and discuss with others before closing or changing the class of the version slot.
