I tried to include different options into the exams2pdf / exams2nops command, but nothing worked for me...

height = 50, width = 50
height = 5, width = 5
height = 0.5, width = 0.5


fig.height = 0.5, fig.width = 0.5

out.width = 0.5

am I using the wrong numbers, or what am I doing wrong? I only have pictures that I generated within R:

```{r Elasticita, echo=FALSE, fig.height = 5, fig.width = 5, fig.path = "", fig.cap = ""}

...
...
...

and I also tried to change the size there, but it is then overwritten I think by the exams2nops command. 

What I did not yet try is modifying the template.

Am I making a mistake with the options in the exams2nops command?

Thank you already!
