report() gains new argument fig.format to specify figure output formats in case of clean=FALSE.
can be vector, e.g. fig.format=c('jpeg','png', 'pdf'), then 3 files are stored for each figure
could someone please test?
It works with the vector. The generated jpeg and png files have a quite low resolution and are as such not really reusable (e.g. in a presentation slide). Can you increase the resolution?
