When I compile this:

---
output: 
  html_document:
    fig_caption: yes 
    dev: CairoSVG

---

```{r}
library(kfigr)
```
```{r test,echo=FALSE,fig.cap="test caption"}
plot(cars)
```

I get figure captions, but when I compile this:

---
output: 
  html_document:
    fig_caption: yes 
    dev: CairoSVG

---

```{r}
library(kfigr)
```
```{r test,echo=FALSE,fig.cap="test caption",anchor='figure'}
plot(cars)
```

...I get no figure caption. I'm using:

      Package Version 
kfigr "kfigr" "1.2"   
knitr "knitr" "1.10.5"

under

> sessionInfo()
R version 3.2.1 (2015-06-18)
Platform: x86_64-apple-darwin13.4.0 (64-bit)
Running under: OS X 10.10.3 (Yosemite)

Thanks!

I'm trying to use kfigr to produce links to figures/chunks, but when I Knit PDF using knitr only the figure/chunk number is shown and not the link to the figure. It works just fine when I Knit HTML, but I'd like to use this on a PDF.

rmarkdown resets the knitr options via opts_knit$restore() after rendering a document so that options changed during one render don't persist across the next document. However, this means that the options and hook definition set by kfigr also get wiped. I need to create a kfigr.initialize() function that users can call at the start of a document to set the anchor hook and kfigr options.

Hi, just trying to understand how kfigr works. In the vignette, at the bottom is says "If there is any confusion, look to the .Rnw source file and all should be clear". But there is no .Rnw source file for me to look at!

I've got a bunch of vignettes that I'm converting from Rnw to Rmd thanks to this package. Individually, they are all Kniting just fine. However, when I use devtools::build_vignettes() or just run a 'check', I get errors:

failed with diagnostics:
First reference must define the type.

Each vignette starts like this:

---
title: "xxx"
author: "xxx"
date: "`r format(Sys.time(), '%d %B, %Y')`"
output:
  rmarkdown::html_vignette:
    fig_height:  6
    fig_width: 6
    toc: yes
    fig_caption: yes
vignette: >
  %\VignetteEngine{knitr::rmarkdown}
  %\VignetteIndexEntry{xxx}
  \usepackage[utf8]{inputenc}

---

```{r setup, echo=FALSE, warning=FALSE, message=FALSE}
library(knitr)
library(kfigr)
library(rmarkdown)
opts_chunk$set(message=FALSE,warning=FALSE,dev="png")
opts_knit$set(eval.after='fig.cap')

Then when I make my figures, I create the chunk like this:

```{r chunk1, anchor="figure", fig.cap=paste0("**Figure ** ",figr('chunk1'),": Dummy plot.")}
plot(1)

Any idea why it would fail during check (with that error) and not when just using the 'Knit' RStudio button? I realize there could be a lot of reasons un-related to your package, but that error I think is unique to kfigr.

Thanks for making this package. It is quite nice. I notice that if I don't specify a caption, I get a default caption related to the chunk name. What I would like to do is capture the text part generated by r figr('chunk-name', type = 'figure') which would be, for instance, "Figure 1" and use it as part of the figure caption. For example, if I said fig.cap = "descriptive caption" it would be really nice if kfigr turned the figure caption into "Figure 1: descriptive caption". I hope this is clear. Yuhui has something similar, but it would operate independently and the numbering may get out of register.

Is there a way to change the language of the output for figr function?
Instead of producing "table 1" I want to use "tabla 1"

Really nice package. Do you have any plans for a .docx implementation? It would be massively useful.
