r - Specify external resource in config.yml -

i have following config.yml file:

dygraphs:   jshead: [js/dygraph-combined.js, js/lodash.js]   cdn:     jshead:       - "http://cdnjs.cloudflare.com/ajax/libs/dygraph/1.0.1/dygraph-combined.js"       - "http://cdnjs.cloudflare.com/ajax/libs/lodash.js/2.4.1/lodash.min.js" 

it sources locally saved js/dygraph-combined.js , js/lodash.js files within working directory.

how rewrite source instead http addresses provided above?

edit

i've found workaround without using config.yml, inserting addresses inside rcharts object property this:

dy1 <- rcharts$new() ... dy1$html_assets$js = c(  "http://cdnjs.cloudflare.com/ajax/libs/dygraph/1.0.1/dygraph-combined.js",   "http://cdnjs.cloudflare.com/ajax/libs/lodash.js/2.4.1/lodash.min.js") ... 

this result in html file indeed contains remote resources:

<script src='http://cdnjs.cloudflare.com/ajax/libs/dygraph/1.0.1/dygraph-combined.js' type='text/javascript'></script> <script src='http://cdnjs.cloudflare.com/ajax/libs/lodash.js/2.4.1/lodash.min.js' type='text/javascript'></script> 

is there still way how achieve same amending config.yml file appropriately?

posting comment answer.

you can pass option cdn = true show or save methods , automatically make use of http links. example,

# display chart using http links dy1$show(cdn = true)  # save chart using http links dy1$save('mychart.html', cdn = true)
