Migrate packages between two R installations in one call

Convenience wrapper around find_routes() and ship(). Matches installations by version string (e.g. "4.5.2") or full Rscript path, then runs the migration. Use ship() directly if you need fine-grained control.

Usage

migrate(from, to, dry_run = FALSE, upgrade = TRUE, mode = "online", ...)

Arguments

from: Version string or Rscript path of the source installation (packages are copied from here).
to: Version string or Rscript path of the target installation (packages are installed into here).
dry_run: If TRUE, return the plan without installing anything. Default FALSE.
upgrade: If TRUE, packages already in the target but at an older version are upgraded as well. Default TRUE.
mode: Transfer mode passed to ship(): "online" (default - reinstall via pak), "offline" (file-copy only, skip packages without a valid source path), or "preserve" (copy for exact version, fall back to a pinned pak spec on failure).
...: Additional arguments passed to ship().

Value

The same named list returned by ship(): plan, results, comparison, dry_run, elapsed_sec.

Examples

if (FALSE) { # \dontrun{
  # dry run first
  migrate("4.5.2", "4.6.0", dry_run = TRUE)

  # for real
  result <- migrate("4.5.2", "4.6.0")
  table(result$results$status)
} # }
