References

I got the code for the recursive function that makes the json hierarchy from someone on stack overflow. I'm sorry I was going to credit them but can no loner find the post. Let me know if it's you!

Examples

data(iris)
jsonOut<-dfToJSON(iris)
fileConn<-file("iris.json")
writeLines(jsonOut, fileConn)
close(fileConn)

jsonOut<-dfToJSON(iris, mode="rowToObject")
fileConn<-file("irisRows.json")
writeLines(jsonOut, fileConn)
close(fileConn)

jsonOut<-dfToJSON(iris, mode="coords")
fileConn<-file("irisCoords.json")
writeLines(jsonOut, fileConn)
close(fileConn)

tree<-dcast(data=iris, Species+Petal.Width ~ .)
jsonOut<-dfToJSON(iris, mode="hierarchy")
fileConn<-file("irisTree.json")
writeLines(jsonOut, fileConn)
close(fileConn)
