Strange behaviour in fromJSON in RJSONIO package

问题 Ok, I'm trying to convert the following JSON data into an R data frame. For some reason fromJSON in the RJSONIO package only reads up to about character 380 and then it stops converting the JSON properly. Here is the JSON:- "{\"metricDate\":\"2013-05-01\",\"pageCountTotal\":\"33682\",\"landCountTotal\":\"11838\",\"newLandCountTotal\":\"8023\",\"returnLandCountTotal\":\"3815\",\"spiderCountTotal\":\"84\",\"goalCountTotal\":\"177.000000\",\"callGoalCountTotal\":\"177.000000\",\"callCountTotal\"

Problems reading JSON file in R

由 我的梦境 提交于 2019-12-12 13:44:46
问题 I have a JSON file (an export from mongoDB) that I'd like to load into R. The document is about 890 MB in size with roughly 63,000 rows of 12 fields. The fields are numeric, character and date. I'd like to end up with a 63000 x 12 data frame. lines <- readLines("fb2013.json") result: jFile has all 63,000 elements in char class and all fields are lumped into one field. Each file looks something like this: "{ \"_id\" : \"10151271769737669\", \"comments_count\" : 36, \"created_at\" : { \"$date\"

Simplifying a POSIX node with RJSONIO::fromJSON()

问题 I have the following vector of double values, x , where each element represents a POSIX date-time x <- c(1417621083, 1417621204, 1417621384, 1417621564, 1417621623) I am using the RJSONIO package, and would like to continue to do so. As an exercise, I'd like to convert these values into JSON text and then read them back into R again, but am having trouble getting the date-time representations into a nice simplified list result. In JSON, the dates need to be in a special format so the values

Converting a matrix/dataframe in R to JSON object with some constraints

问题 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

Parsing data frame to JSON (via RJSONIO)

由 核能气质少年 提交于 2019-12-08 02:06:31
问题 I have an issue with RJSONIO. I have a data frame like df df <- data.frame(a = c(1:3), b = c(4:6), c = c(7:9) ) df a b c 1 1 4 7 2 2 5 8 3 3 6 9 Now what I need is to use this data frame and generate the rows in the following JSON structure. So in the end it would look something like this: { "job_id": "1", "page": "1", "rows": [ { "row": [ "1", "4", "7" ] }, { "row": [ "2", "5", "8" ] }, { "row": [ "3", "6", "9" ] } ] } I started with this chunk of code but there is problem with quotes inside
