rjson

REDITED: I have to convert a matrix in R to a JSON object with some structure in it. I am using the rjson package. Through an example, let me illustrate what I want. My specific case is the output of a recommender system code in R where the X2 X3 are the 2 closest items to a particular item X1. Also, X4,X5 are the scores of similarity associated with (X1,X2) and (X1,X3) for that row. I want all the recommended items for every item as JSON objects and every item along with its recommended JSON object- items as a bigger JSON objects.The scores should also be incorporated into the JSON structure.

I have a json text file which reads {"type":"session.ended","v":2,"post.source":"1306210600-col001.sv1.movenetworks.com:2097#5","post.ip4":"75.114.187.146","post.rtime_secs":1371794661,"post.rtime_text":"2013-06-21 06:04:20","post.time_secs":1371794596,"post.time_text":"2013-06-21 06:03:16","post.time_date":"2013-06-21","post.time_hour":6,"post.late_secs":65,"id.session":"3625657","id.sub":"2370b726-b96e-11e2-b3eb-1231380e1adf","id.partner":"0CB48A664E514CA48D378D152574EDBB","id.service":"BBTV (CBD46B77)","device.make":"Roku","device.model":"3050X","device.info":"Roku;3050X","device.serial":

I want to play with data that is now saved in JSON format. But I am very new to R and have little clue of how to play with data. You can see below what I managed to achieve. But first, my code: library(rjson) json_file <- "C:\\Users\\Saonkfas\\Desktop\\WOWPAPI\\wowpfinaljson.json" json_data <- fromJSON(paste(readLines(json_file), collapse="")) I was able to the data: for (x in json_data){print (x)} Although output looks pretty raw: [[1]] [[1]]$wins [1] "118" [[1]]$losses [1] "40" # And so on Note that the JSON is somewhat nested. I could create tables with Python, but R seems much more

I have a data frame that I like to convert to json format: my data frame called res1: library(rjson) structure(list(id = c(1, 2, 3, 4, 5), value = structure(1:5, .Label = c("server1", "server2", "server3", "server4", "server5"), class = "factor")), .Names = c("id", "value"), row.names = c(NA, -5L), class = "data.frame") when I do: toJSON(res1) I get this: {"id":[1,2,3,4,5],"value":["server1","server2","server3","server4","server5"]} I need this json output to be like this, any ideas? [{"id":1,"value":"server1"},{"id":2,"value":"server2"},{"id":3,"value":"server3"},{"id":4,"value":"server4"},{
