How to automatically number figures in Note

#1

You can number figures automatically in Note using an inline R code. The idea is to create an R variable that holds the current number and increment one after showing each figure. Here is a note example. (somehow just fignum++ doesn’t work in the inline R code.)

`r fignum <- 0;`

Picture `r fignum <- fignum+1; fignum;`

Picture `r fignum <- fignum+1; fignum;`

Picture `r fignum <- fignum+1; fignum;`

If you run this note, it will show the following text in the preview.
