Resizing external image in Rmarkdown: html vs. ioslides output -


i'm using external images in rmarkdown document meant rendered ioslides , need resize them.

doing html way works both when knit ioslides , html_document. 

<img src="image.png" style="height: 200px"/>

doing markdown way below works when knit html_document not when knit ioslides (i.e., image isn't resized).

![](image.png){width=200px}

my question is: how can make markdown resizing approach work when output ioslides?

python - Best design pattern for collection of objects -

i have following architecture: +-----------------+ | collection | | | | | | | | | +-----------------+ | ^ | | create() | | | | v | getitem(b) +------------+ | | item | | | | | | +------+ | | +------------+ a class managing collection of items, creates items. , these items may need other items collection. the actual code in python, , collection passes parameter created item . see it, bad practice. improvement can see pass few functions of collection needed item , instead of whole instance. for example: class collection: getitem(self, id): ... createitem(self, id): item = item(id, self) # <-- pass self ... class item: __init__(self, id, col): ... col.getite...
