R do.call(rep, input) %>% strsplit(NULL) %>% sapply(sample) %>% apply(2, paste, collapse = "")

final output from R returns to javascript as parsed JSON

Javascript var R = require(“r-script");

var out = R("example.R") .data("hello world", 20) .callSync();

data is passed to R as variable input

R attach(input[[1]])

df %>% mutate(group = cut(rating, nGroups)) %>% group_by(group) %>% summarize_each(funs_(fxn)) %>% transmute(group = as.character(group), rating, advance)

Javascript var R = require(“r-script");

R("example/ex-async.R") .data({df: attitude, nGroups: 3, fxn: "mean" }) .call(function(err, d) { if (err) throw err; console.log(d); });

needs to the rescue

A simple wrapper around library and install.packages

that loads/attaches packages and automatically installs

any that are missing
