安装的R github软件包不包含R/sysdata.Rda [英] Installed R github package does not include R/sysdata.Rda

问题描述

我有一个R github软件包，可以使用devtools::install_github("jwilliman/ethnicNZ")(或remotes::install_github)成功"安装.在github上，软件包包含使用命令usethis::use_data(ethnic05, internal = TRUE)保存为'R/sysdata.Rda'的内部数据.

I have an R github package that I can 'successfully' install using devtools::install_github("jwilliman/ethnicNZ") (or remotes::install_github). On github the package contains internal data saved as 'R/sysdata.Rda' using the command usethis::use_data(ethnic05, internal = TRUE).

但是，安装后，'../Library/ethnicNZ/R'文件夹中缺少文件'sysdata.rdb'和'sysdata.rdx'，当从软件包中运行命令ethnicNZ::find_data()时，我得到了错误Error in ethnicNZ::find_data() : object 'ethnic05' not found. (这些文件存在，如果我直接从本地git安装软件包，则该命令有效).

However, after installation the files 'sysdata.rdb' and 'sysdata.rdx' are missing from the '../Library/ethnicNZ/R' folder, and when running the command ethnicNZ::find_data() from the package I get the error Error in ethnicNZ::find_data() : object 'ethnic05' not found. (These files are present, and the command works if I install the package directly from my local git).

这可能与在包函数中访问sysdata.rda 和R程序包的构建/安装错误:找不到对象"即使我在R/sysdata.rda 中有它，但都没有一个可接受的答案.希望我的示例可以重现，以便其他人进行故障排除.

This is possibly a similar issue as accessing sysdata.rda within package functions and R Package Build/Install Error: "object not found" even though I have it in R/sysdata.rda, but neither has an accepted answer. And hopefully my example is reproducible enough for others to troubleshoot.

编辑

我刚刚在安装时注意到我收到错误消息

I just noticed on installation I get the error

   Subdirectory 'R' contains invalid file names:
     'sysdata.Rda'

为什么这是无效的，我该如何避免呢?

Why is this invalid, and how can I avoid it?

推荐答案

情况很重要！该文件必须名为"sysdata.rda"而不是"sysdata.Rda".

Case matters! The file must be called 'sysdata.rda' not 'sysdata.Rda'.

我发现我以前将数据另存为save(ethnic05, filename = "sysdata.Rda")，后来又改为使用usethis::use_data(ethnic05, internal = TRUE). usethis::use_data保存在先前的文件上，但没有更正扩展名的大小写.在恢复正确的sysdata.rda之前，我必须删除'sysdata.Rda'，提交并推送到github.

I discovered that I'd previously saved the data as save(ethnic05, filename = "sysdata.Rda"), then later changed to using usethis::use_data(ethnic05, internal = TRUE). usethis::use_data saved over the previous file but did not correct the case of the extension. I had to delete 'sysdata.Rda', commit and push to github before reinstate the correct sysdata.rda.

如 https.1.1.5节中所列://cran.r-project.org/doc/manuals/r-release/R-exts.html ，

"R子目录仅包含R代码文件.要安装的代码文件必须...具有扩展名13 .R，.S，.q，.r或.s....两个例外允许:如果R子目录包含文件sysdata.rda.

"The R subdirectory contains R code files, only. The code files to be installed must ... have one of the extensions13 .R, .S, .q, .r, or .s. ... Two exceptions are allowed: if the R subdirectory contains a file sysdata.rda.
