Hi I have the following markdown chunk:

```{r, echo=FALSE,warning=FALSE,message=FALSE,error=FALSE}
lapply(obj,function(x) plot(x,main="some plot") box() axis(1,at=seq(0,25,by=1))
```

The output is multiple plots. However I also get the console message in the pdf document underneath the plots.

<Plot 1> nice plot 1!
<Plot 2> nice plot 2!

-- nasty horrible console output
## [[1]] 
01.2882829 

## [[2]]
120.29393933

I have tried echo/warning/error/message = FALSE, but neither of these suppress the console output

please help!

try this:

{r, echo=FALSE,results='hide',fig.keep='all'}
lapply(obj,function(x) plot(x,main="some plot") box() axis(1,at=seq(0,25,by=1))
