Pass data from R to WebPPL

[mhtess]

If you have a data frame df that might look like

Participant	Condition	Response
1	A	0.4
1	B	0.8
2	A	0.2

You could convert it into a list of js objects e.g.

[
{
  participant: 0,
  condition: "A",
  response: 0.4
},
{
  participant: 0,
  condition: "B",
  response: 0.8
},
{
  participant: 1,
  condition: "A",
  response: 0.2
}, 
...
]

And use jsonlite to serialize it. You could prepend the webppl model with something like "var data = " + jsonlite::toJSON(df)
