libcurl error when using htmlwidgets::saveWidget along with plotly::partial_bundle without an internet connection #2498
Description
Running the ?plotly::partial_bundle example without an internet connection available results in the below error.
I think it used to work without accessing https://cdn.plot.ly ?
As a workaround I'm now using curl::has_internet to check whether I can use partial_bundle.
Example:
library(plotly)
p <- plot_ly(x = 1:10, y = 1:10) %>% add_markers()
save_widget <- function(p, f) {
owd <- setwd(dirname(f))
on.exit(setwd(owd))
htmlwidgets::saveWidget(p, f)
mb <- round(file.info(f)$size / 1e6, 3)
message("File is: ", mb," MB")
}
f1 <- tempfile(fileext = ".html")
f2 <- tempfile(fileext = ".html")
save_widget(p, f1)
save_widget(partial_bundle(p), f2)
Error:
