export_graph() does nothing
The following code does nothing for me.
library("DiagrammeR")
# Create node data frame (ndf)
ndf <- create_node_df(n = 7,
label = c("Contains\n longitudinal data", "Exclude",
"Data is available\n online", "Exclude",
"Author(s) responded to\n initial e-mail", "Exclude",
"Use"),
y = 7:1,
x = rep(1:2, times = 7),
shape = "rectangle", fillcolor = "white", fixedsize = FALSE)
# Create an edge data frame (edf)
edf <- create_edge_df(from = rep(c(1, 3, 5), each = 2),
to = c(2, 3, 4, 5, 6, 7),
label = rep(c("yes", "no"), times = 3))
# Create graph
a <- create_graph(nodes_df = ndf, edges_df = edf)
# a %>% render_graph()
a %>% export_graph(file_name = "dataflow-1.pdf", file_type = "pdf")

Am I doing something wrong? Would really appreciate some help :cake: :cat:
Hi @HeidiSeibold , sorry for the trouble with export_graph(). The way to make this work (I hope!) is to first install the DiagrammeRsvg package (it's available from CRAN). Let me know if that solves the problem.
Note to self: I should have is a message stating that it needs to be installed (if it's not present).
Unfortunately I cannot check because the installation failed, see here: https://github.com/jeroen/V8/issues/49
Will keep you updated.
Installation worked now, but I still have the same issue (see jeroen/V8#48)

I have the same issue, in this case with a PNG file output. Loading DiagrammeRsvg does not, unfortunately, fix the problem.
Additionally, an error message produced is "Error in loadNamespace(name) : there is no package called ‘rsvg’" (Which I presume is because rsvg is not a dependency in the DESCRIPTION file to enable non-manual loading?)
I have a similar issue with the export_svg function...:
library(DiagrammeR)
svg <- export_svg(grViz('digraph{a->b; c->a; c->b; c->d;}'))
#
# Fatal error in ../src/platform-linux.cc, line 782
# CHECK_EQ(0, result) failed

I encountered this issue as well. export_graph() failed to output a PDF without returning a warning or error.
After additionally installing {rsvg} and {DiagrammeRsvg}, it worked.
The current logic doesn't correctly emit the intended error message.
Hi It finally created the png for me after also adding the library rsvg.
I have: library(DiagrammeR) library(DiagrammeRsvg) library(rsvg)
I can confirm this works only if you load both DiagrammeRsvg and rsvg. If not, export_graph() does nothing.
Maybe you need to install rsvg also @HeidiSeibold
Ah yes, that works. Thank you :pray: :clap:
Maybe it would be helpful for users to get a warning if they don't have the package installed + loaded. :thinking:
library(DiagrammeR) library(DiagrammeRsvg) library(rsvg)
Loading all these as @midraed suggested worked for me too. +1 for adding warning message as suggested by @HeidiSeibold :)
