pander.lm tables within slidify

Question

I'm having difficulty in getting pander tables to render in a slidify document (specifically with a call to pander.lm).

For example, the below works

```{r panderWorks, results = "asis"}
id <- rep(1:3, each = 2)
condition <- rep(c("A", "B"), 3)
score <- rnorm(6, 10, 3)
d <- data.frame(id, condition, score)

library(pander)
pander(d, style = "rmarkdown")
```

while the following does not

```{r panderFails, results = "asis"}
data(iris)
pander(lm(Sepal.Width ~ Species, data = iris), 
   style = "rmarkdown")
```

Note that I actually can get the first chunk to render correctly without the results = "asis" option, but that's worked for me in the past. I've tried changing many options and still no luck. It's also worth noting that I have no problem getting this to render in a standard rmarkdown document. It's only within slidify that I have issues.

I'm working within the io2012 framework, with the highlight.js highlighter and the zenburn highlight theme. I've loaded the mathjax widget and the mode is selfcontained.

Below I've attached my output from sessionInfo().

Any ideas?
