Every time I try to plot anything with RStudio Cloud using the webshot package I obtain an error. An example:
#install webshot
library(webshot)
webshot::install_phantomjs()
# Make the graph
my_graph=wordcloud2(demoFreq, size=1.5)
# save it in html
library("htmlwidgets")
saveWidget(my_graph,"tmp.html",selfcontained = F)
# and in png
webshot("tmp.html","fig_1.png", delay =5, vwidth = 480, vheight=480)
The error says:
QXcbConnection: Could not connect to display :0
PhantomJS has crashed. Please read the bug reporting guide at
