file("") only supports open = "w+" and open = "w+b" about recharts

Did you install this package or were you trying to load it via devtools::load_all()? Can you provide devtools::session_info() and RStudio version?

I was trying to load it via devtools::load_all(). Rstudio works if I install it = =
So what's the difference between devtools::load_all() and install? Why it works in Rgui and does not work in Rstudio if I use devtools::load_all()?

Rstudio version: 0.99.467

Bottom line: don't use load_all() for packages based on htmlwidgets. If you care about the technical details: rstudio/leaflet#52

I see, thank you.
