Hello. I am drawing a graph using graphviz. It works but now, I am trying
to use some palettes from the RColorBrewer pakcage. Any idea why this
diagram works when the code (in .Rmd) is
```{r, engine='dot', echo=F}
digraph unix{
size=30;
ratio=compress;
param [label=" Contrastes paramétricos ", shape=oval,
style="filled,rounded,diagonals",
fillcolor=dodgerblue3,
fontcolor=gray90];
```
but it doesn't work if I try to use some colors of any palette
```{r, echo=FALSE}
library("RColorBrewer")
colores <- brewer.pal(11,"PiYG")
```
```{r, engine='dot', echo=F}
digraph unix{
size=30;
ratio=compress;
param [label=" Contrastes paramétricos ", shape=oval,
style="filled,rounded,diagonals",
fillcolor=colores[1],
fontcolor=gray90];
```
Thank you very much!!
