我正在查看函数install_github，我认为它属于库devtools。
算是吧，它属于remotes库。
当在RStudio中触发错误时，您可以通过跟踪堆栈来进行故障排除，我可以主动应用这种逻辑吗？
是否有函数traceFunction()或其他东西可以看到返回顺序library::method调用的列表？
如果这个函数不存在，它会存在吗？

traceFunction("install_github");

为了澄清，我对引用的包执行了git clone。devtools包含以下内容：

#' @importFrom remotes install_github
#' @rdname remote-reexports
#' @export
install_github <- with_pkgbuild_build_tools(with_ellipsis(remotes::install_github))

其中remotes具有以下内容：

#' # To install from a private repo, use auth_token with a token
#' # from https://github.com/settings/tokens. You only need the
#' # repo scope. Best practice is to save your PAT in env var called
#' # GITHUB_PAT.
#' install_github("hadley/private", auth_token = "abc")
#'
#' # To pass option arguments to `R CDM INSTALL` use `INSTALL_opts`. e.g. to
#' install a package with source references and tests
#' install_github("rstudio/shiny", INSTALL_opts = c("--with-keep.source", "--install-tests"))
#' }
install_github <- function(repo,
                           ref = "HEAD",
                           subdir = NULL,
                           auth_token = github_pat(quiet),
                           host = "api.github.com",
                           dependencies = NA,
                           upgrade = c("default", "ask", "always", "never"),
                           force = FALSE,
                           quiet = FALSE,
                           build = TRUE, build_opts = c("--no-resave-data", "--no-manual", "--no-build-vignettes"),
                           build_manual = FALSE, build_vignettes = FALSE,
                           repos = getOption("repos"),
                           type = getOption("pkgType"),
                           ...) {

  remotes <- lapply(repo, github_remote, ref = ref,
    subdir = subdir, auth_token = auth_token, host = host)

  install_remotes(remotes, auth_token = auth_token, host = host,
    dependencies = dependencies,
    upgrade = upgrade,
    force = force,
    quiet = quiet,
    build = build,
    build_opts = build_opts,
    build_manual = build_manual,
    build_vignettes = build_vignettes,
    repos = repos,
    type = type,
    ...)
}

它调用install_remotes，通过搜索存储库remotes中的所有“.R”文件，我不容易找到它。
