How do I suppress the warning from including a library when using knitr in R?
knitr, r, r-markdown
Solution
Set the following chunk options `message=FALSE, warning=FALSE, include=FALSE`.
Problem
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: How do I suppress the warning from including a library when using knitr in R? Thanks in advance.
