## Setup
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
library(DiagrammeR)
```
## R Markdown
```{r}
mermaid("
graph TB;
a ==> b;
b ----> c[apple]
")
```
For some reason the 2nd line in the graph doesn't seem to be rendering because its not realizing the 'longer arrow'. Anyone know how to solve this trivial problem
Looks like this depends on how large your network graph is. You can look up the documentation of the package in Rstudio by entering ??DiagrammeR::mermaid in the console.
An example from the package shows 10 nodes creates longer arrows than just A->B
Doesn't look like b ----> c[apple] is proper syntax for longer arrows, to what I read in the package docs.
grViz("
digraph a_nice_graph {
# node definitions with substituted label text
node [fontname = Helvetica]
a [label = '@@1']
b [label = '@@2-1']
c [label = '@@2-2']
d [label = '@@2-3']
e [label = '@@2-4']
f [label = '@@2-5']
g [label = '@@2-6']
h [label = '@@2-7']
i [label = '@@2-8']
j [label = '@@2-9']
# edge definitions with the node IDs
a -> {b c d e f g h i j}
}
