Highcharter doesn't work in updated Rstudio & R.

[jhk0530]

I tried this demo code.

and it doesn't plot in viewer panel in R studio.

Instead, it takes a lot of CPU usage and crashed.

When I run this code in RGui (not R studio) it worked.

So I think this doesn't related with updated version of R itself.

highchart() %>% 
  hc_chart(type = "column") %>% 
  hc_title(text = "A highcharter chart") %>% 
  hc_xAxis(categories = 2012:2016) %>% 
  hc_add_series(data = c(3900,  4200,  5700,  8500, 11900),
                name = "Downloads")

I'm not sure about whether this problem is caused by Rstudio or Highcharter.

• Rstudio Version 1.2.5042
• Highcharter Version 0.7.0.9001

Hi @jhk0530

I also figured there was an issue with other highcharts I had.

My conclusion was that the problem is related to R 4.0.0, since with the latest R studio and R 3.6.3 it all works, but not with R 4.0.0.

You can see the changes within R 4.0.0 here.

I couldn't track the exact issue, but I suspect has to do with the plot function changes, but I could be wrong

Hi @jbkunst . Do you know what update in R 4.0.0 are crashing highcharts?

Hi @jhk0530 @mtyszler

@jhk0530, what OS do you have? I tested on windows and I replicated having the same behaviour.

[mtyszler]

I used in windows 10.

I compared the older R studio to the newest R studio, both in combination with R 4.0 and R 3.6.

The problem happened only with R 4.0, regardless of the R studio version.

[jhk0530]

same I used win 10.

I think this isn't only issue with highcharter.

some shiny functions also make Rstudio viewer panel to crash.

[jbkunst]

Doy you have a reprex for thas shiny functions? I'll open an issue to https://github.com/rstudio/rstudio

[jhk0530]

here's one example with my own CRAN package shinyCyJS.

install.packages('shinyCyJS')
library(shinyCyJS)
shinyCyJS(list(buildNode('a'), buildNode('b'), buildEdge('a','b')))

It should plot graph in viewer panel like below ( this is from 3.6.3 )

but it frozen in R 4.0

I found there's already issue with this, include DT, leaflet.
rstudio/rstudio#6737

[mtyszler]

Check if rstudio/rstudio#6737 fixes it

[jhk0530]

It seems this issues has fixed in Rstudio version 1.3.

I'll close this issue
