R 错误\在文档对象中找到用法行

我的包裹无法通过R CMD检查。我正在使用

devtools

version1.9.1和

Roxygen2

version4.1.1。我的问题如下：

Bad \usage lines found in documentation object 'my_fn':


Functions with \usage entries need to have the appropriate \alias
entries, and all their arguments documented.
The \usage entries must correspond to syntactically valid R code.
See chapter 'Writing R documentation files' in the 'Writing R
Extensions' manual.

#' My function
#'
#' Extracts data from the database in order to produce plots and

my_fn <- function (operate,
                   crl,
                   nt,
                   ref.coef = list(fit = function(crl) {
                     -1 + 0.05 * crl - 0.0002 * crl ^ 2
                   },
                   sd.reg = 0.5),
                   ...) {
# Some cool stuff
}

\usage{

      ref.coef = list(fit = function(crl) {     -1 + 0.05 * crl - 0.0002
  * crl^2 }, sd.reg = 0.5), ...)
}
\arguments{
\item{operate}{A vector of ID codes.}

\item{crl}{A vector of crl data.}

\item{nt}{A vector of nt data.}

\item{ref.coef}{Reference coefficient for gestational age.}

\item{...}{Further arguments passed to or from other methods.}
}
\description{

}

所以，正如你所看到的，它实际上并没有给我任何关于问题发生地点的指示。只有两个空格

我的职能如下：

有什么想法是失败的吗？

当我从文档和函数中删除整个

ref.coef

时，没有错误

当我将它保存在roxygen文档和函数中时，roxygenize它，然后尝试添加

sd.reg

（看看它是否只是一个解析错误），它仍然在呜咽

这看起来不像是roxygen问题，但更像是

R CMD check

处理Rd文件的方式

临时解决方案可能是采取以下措施：

ref.coef = REF.COEF(),

然后

REF.COEF <- function() {
  list(fit = function(crl) {
    -1 + 0.05 * crl - 0.0002 * crl ^ 2
  },
  sd.reg = 0.5)
}

---

REF.COEF SD.reg不在@param中，但
SD.reg
不是一个参数，它是名为
REF.COEF
的列表的一部分。我尝试为
SD.reg
和
fit
添加
@param
标记，但我得到了完全相同的问题。谢谢@hrbrmstr，我将尝试一下。这很奇怪，因为我有另一个函数，它与这个函数非常相似，它也以同样的方式使用
ref.coef
参数，但我对这个参数没有任何问题……可能是某种深奥的组合导致Rd解析器发疯。如果我今天有更多的周期（我有几个“监听”的骗局电话），我会看看所说的组合可能是什么。
