After updating to the latest DiagrammeR from CRAN, my vignette is not building any more, giving me the following error:
pandoc.exe: Could not fetch .\R\win-library\3.2\DiagrammeR\htmlwidgets\lib\mermaid\dist#arrowhead
If I run the code in R (not in markdown), it does not produce an error, but the arrowheads are not displayed any more.
I think this is related to this commit:
mermaid + pandoc bug in DiagrammeR v0.8 and 0.8.1 causes `eventDiagram` and `objectDiagram` to fail during vignette build (therefore fails CMD check). rich-iannone/DiagrammeR#139 * workaround: remove DiagrammeR from Imports * check for Diagrammer v 0.7 namespace; if found, use it; if not, warn user with instructions on installing 0.7
attempt to resolve issue rich-iannone#139 * commit 008bb33 added `.mermaid` to each css element, but these additions were wiped out in commit 8a99996 TO DO * not sure why arrowhead was deleted (dbdabc1) -- unable to reproduce pandoc error no windows. try on linux. * R CMD check throws a bunch of warnings
