In umx: Structural Equation Modeling and Twin Modeling in R

Resolve a platform GenomicMx binary URL from the umx Release tag

Description

Uses the GitHub API for the Release with tag genomicmx and returns a single download URL matching this session's OS, arch and R version. No new package dependencies (base R url() + regex on the JSON).

Usage

xmu_genomicmx_binary_url(
  tag = "genomicmx",
  verbose = getOption("umx.verbose", FALSE)
)

Arguments

tag	Release tag to query (default "genomicmx").
verbose	Logical; if TRUE, message diagnostics on no match.

Details

Assets are expected to be named OpenMx_<Version>_<SHA7>_<OS>_<Arch>_R<major>.<minor>.<ext> (e.g. OpenMx_2.50_abc1234_Linux_x86_64_R4.6.tgz). The resolver prefers an exact R<major>.<minor> match and an exact arch match on macOS (arm64 vs x86_64); it does not fall back across arch or R. Legacy assets without an R token are still considered but ranked lower. Returns NULL when no matching asset is found or the API is unreachable.

Value

Character scalar URL or NULL.
