Issue exporting mermaid diagram in RStudio

[morsem]

I'm using RStudio Version 0.98.1103. Nothing actually saves when I use the RStudio Export function to "Save as Image." This might be a problem on RStudio's end, or I'm just experiencing some odd quirk.

same issue here. on ubuntu 14.04 64-bit.

to clarify - markdown export works fine. export doesn't work at all. copy to clipboard sort-of works, but the screenshot missed a bit: (this is the actual content of the clipboard after clicking on "clipboard")

This has been happening to me as well for Graphviz diagrams. Saving the image doesn't actually write the file. @jjallaire : is it possible that this is a bug affecting all htmlwidgets or recent builds of RStudio? I think I was able to save images before (however, not totally sure).

I just tested this with the RStudio Preview build (v0.99.386, http://www.rstudio.com/products/rstudio/download/preview/) and it worked fine on Windows, Mac, and Linux. Here's the code I'm using:

library(DiagrammeR)

boxes_and_circles <- "
digraph boxes_and_circles {

# several 'node' statements
node [shape = box]
A; B; C; D; E; F

node [shape = circle,
fixedsize = true,
width = 0.9] // sets as circles
1; 2; 3; 4; 5; 6; 7; 8

# several 'edge' statements
A->1 B->2 B->3 B->4 C->A
1->D E->A 2->4 1->5 1->F
E->6 4->6 5->7 6->7 3->8

# a 'graph' statement
graph [overlap = true, fontsize = 10]
}
"

grViz(boxes_and_circles)

What platform are you on and what is the exact behavior you are seeing?

I just downloaded the latest preview v0.99.386. Now slightly different problem - clipboard and export now both work, but seem to take a screenshot but the screenshot is not quite the same area as the plot. Here I am pasting the export; the clipboard looks exactly the same. Markdown knit to html works fine.

So my problem is not quite the same as the other two colleagues.

I should add this does not happen with say plot(1:10) or ggplot(1:10)

Hmm...this works correctly for me under the same configuration.

The way we implement this is to take a screenshot of the region of the page that corresponds to the widget image. Clearly there is some sort of offset problem here, perhaps caused by a custom Gnome/Unity theme? (just a wild guess). If you provide more info about your configuration we may still be able to reproduce locally.

that is probably the reason - I have some kind of messed-up desktop which is mate 1.8.2 but I think it is contaminated with xfce or something like that. I will check next time I log into gnome-shell. thanks.

The window system measurements are probably off so when Qt goes to address a part of the Window it gets the wrong offset for the size(s) of the Window c hrome. If it's truly some sort of mal-configuration I don't know if there's a way for us to fix this.

I get this problem too with Mac El Capitane 10.11.3 and R Studio Version 0.98.1091 and DiagrammeR 0.8.2. It only affects plots from DiagrammeR. What should I do about it?
