Error when saving html visual (R custom)

[Booth070]

When I run the custom visual in PBI I get this error from internalsavewidget:

Error in system.file(config, package = package) :
'package' must be of length 1
Calls: internalSaveWidget ... getDependency -> <Anonymous> -> inherits -> system.file
Execution halted"

The code is working fine and producing the expected output when I have tested it in R so I do not understand where it comes from. The plot is created from this line:

p<- ggplotly(p) %>%
layout(annotations = list(x = 1.5*y.o, y = round(ylims,1), text = paste0("p-value: ",pvalue), showarrow = F))

internalSaveWidget(p,"out.html")

I  can only wonder if the "%>%" is messing some things up?

Thanks in advance.

Do you have any updates on the case,

Have you also included the dplyr library?

libraryRequireInstall("dplyr");

Perfect, now it works - thanks so much!
