[英]Using inst/extdata with vignette during package checking R 2.14.0
I have a package which contains a csv file which I put in inst/extdata per R-exts. 我有一个包含一个csv文件的包,我把它放在每个R-exts的inst / extdata中。 This file is needed for the vignette. 小插图需要此文件。 If I Sweave the vignette directly, all works well. 如果我直接拍出小插图,一切都很好。 When I run R --vanilla CMD check however, the check process can't find the file. 但是,当我运行R --vanilla CMD检查时,检查过程找不到该文件。 I know it has been moved into an .Rcheck directory during checking and this is probably part of the problem. 我知道在检查期间它已被移动到.Rcheck目录中,这可能是问题的一部分。 But I don't know how to set it up so both direct Sweave and vignette building/checking works. 但我不知道如何设置它所以直接Sweave和vignette建立/检查工作。
The vignette contains a line like this: 小插图包含如下行:
EC1 <- dot2HPD(file = "../inst/extdata/E_coli/ecoli.dot",
node.inst = "../inst/extdata/E_coli/NodeInst.csv",
and the function dot2HPD accesses the file via: 并且函数dot2HPD通过以下方式访问文件:
ni <- read.csv(node.inst)
Here's the error message: 这是错误消息:
> tab <- read.csv("../inst/extdata/E_coli/NodeInst.csv")
Warning in file(file, "rt") :
cannot open file '../inst/extdata/E_coli/NodeInst.csv': No such file or directory
When sourcing ‘HiveR.R’:
Error: cannot open the connection
Execution halted
By the way, this is related to this question but that info seems outdated and doesn't quite cover this territory. 顺便说一下,这与这个问题有关,但这些信息似乎已经过时,并没有完全覆盖这个领域。

Have you tried using system.file
instead of hardcoded relative paths? 您是否尝试过使用system.file
而不是硬编码的相对路径?
EC1 <- dot2HPD(file = system.file("inst", "extdata", "E_coli", "ecoli.dot", package = "your_package+name"))
node.inst <- system.file("inst", "extdata", "E_coli", "NodeInst.csv", package = "your_package_name")
