How do I suppress the warning from including a library when using knitr in R?

Question

I'm using knitr to generate HTML output of my work while using R.

The problem is, when I include a library, such as

library(car)

my R markdown document includes the warning:

## Warning: package 'car' was built under R version 2.15.3

I have tried these solutions, but none work:

```{r }
invisible(library(car)

and

```{r message = FALSE, warnings = FALSE}

along with

```{r results = 'hide'}

and unfortunately none of these options work.

Further options I've tried, and the actual knitr output follow:
