[Rd] Problem building rmarkdown vignettes with child
Dear Community, I have an Rmarkdown vignette with optional child documents. Since all markdown files in the vingette folder are build when executing R CMD build I did place the child documents in /inst/ParametrizedReportChid/ so they are excluded from the build. I do reference them from the markdown file in the vignette folder by: ```{r referencingChildDocument} child_docs <- "Grp2Analysis_MissingInOneCondtion.Rmd" if(!sum(NAinfo$nrProteins > 0) > 0){ child_docs <- "Grp2Analysis_Empty.Rmd" } child_docs <- system.file("ParametrizedReportsChild",child_docs,package = "SRMService") ``` ```{r includeMissingInOne, child = child_docs} ``` When running devtools::clean_vignettes() devtools::build_vingettes() devtools::build() # or R CMD build PACKAGE all works fine. However, devtools::clean_vignettes() devtools::build() # or R CMD build PACKAGE Fails with the diagnostic: ** building package indices ** installing vignettes ?Grp2Analysis.Rmd? using ?UTF-8? Error in eval(x, envir = envir) : object 'child_docs' not found Warning in readLines(if (is.character(input2)) { : cannot open file './child_docs': No such file or directory Quitting from lines 387-388 (./child_docs) Error in readLines(if (is.character(input2)) { : cannot open the connection ERROR: installing vignettes failed I did try to use the base::system.file and devtools::system.file function but both generate the same error. The package and vignette can be found here: https://github.com/protviz/SRMService Have a great day Best regards Witek -- Witold Eryk Wolski

It's a long vignette, and not easy to spot where things are going wrong. I'd recommend backing up the original, and just cutting things out until the only thing left is the error. Hopefully then it will be clear what's wrong.
