I'm trying on a simple knitr markdown "exercise". What I want to do is to simply source my R script file and output some of the data, e.g. the mean of a vector.
My code
```{r, echo = FALSE}
summary(cars)
source("GETPrices.R")
x <- BooliReq()
mean(x$sold$listPrice)
```
Firstly, the source ("GETPrices.R")
generates an ugly
Attaching package: 'jsonlite'
The following object is masked from 'package:utils':
View
in the output file. How can this be prevented?
Secondly, when I e.g. try to output the mean value (see code above), all I get is
Warning in mean.default(x$sold$listPrice): argument is not numeric or
logical: returning NA
Outputting the mean in this way works fine though in console. So what is the issue?

For the first error, use the options:
{r, echo = FALSE, message=FALSE,warning=FALSE}
