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

See here:

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:

On Mac, from CRAN version and github version

Incidentally, arrowheads are not displaying when rendering mermaid diagrams within R scripts, could be a related issue?

mermaid + pandoc bug in DiagrammeR v0.8 and 0.8.1 causes `eventDiagram`
and `objectDiagram` to fail during vignette build (therefore fails CMD


* 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

Is there any way to bring arrowhead back to the package?
I am a new user of this package, I run some examples at DiagrammeR website , none of arrowheads are displayed in the figures.
