Create Multiple JSON files from Dataframe R

Question

I have a dataframe and I want to create individual JSON files and use one of the column names to name each of the JSON files.

The following code will create multiple CSV files, but instead I want JSON. I am using the iris dataset from plyr.

library(plyr)
d_ply(iris, .(Species), function(x) write.csv(x, file = paste(unique(x$Species), ".csv", sep = "")))

Answer 1

As Nicola suggests, there are many packages for producing JSON. Adapting your d_ply code:

library(jsonlite)
d_ply(iris, .(Species), function(x) {
    writeLines(toJSON(x), file = paste0(x$Species[1], ".json"))
})
