func EnsureInstalled ¶

func EnsureInstalled(ctx context.Context, be backend.Backend,
	image, version, cachePath string) (string, error)

EnsureInstalled downloads the pak R package to the cache directory if not already present. Returns the path to the cached pak package directory (suitable for mounting into build containers).

The cached pak is a fully installed R package tree — the build container adds it to .libPaths() and calls pak functions directly.
