In R and knitr, can I suppress the message of readOGR?

Question

I\'m building small report using R & knitr, sending the output to pdf.

I\'m using several shape files in my analysis and whenever I use readOGR func

Answer 1

The "knitr" way to do this would be to use results = 'hide'. Borrowing from @SimonO101's example data, try:

```{r, results='hide', echo=FALSE, message=FALSE}
library(rgdal)
dsn <- system.file("vectors", package = "rgdal")[1]
cities <- readOGR(dsn=dsn, layer="cities")
```
