Hi I would like to change chunk options, mid chunk, without having to create a new chunk..
running the following code I would expect to get two very different size outputs, but for some reason this does not seem to be the case.
Also the second plot doesn't plot at all...(it does when you change it to plot(2:1000)...but either way the second output is the same size as the first. both fig.width=7
. What am I doing wrong?
Pls note the importance of 'mid chunk' the reason for this is that I would like to change the chunk options several times when running a function to get different outputs of different sizes.
```{r}
sessionInfo()
opts_chunk$set(fig.width=3)
plot(1:1000)
opts_chunk$set(fig.width=10)
plot(1:1000)
```
the sessionInfo output is as follows:
