I am trying to pull data from quandl website. I am using jsonlite library of R to pull the data. It's working fine. But, when I converting it to dataframe, it's throwing me following error
Error in (function (..., row.names = NULL, check.rows = FALSE, check.names = TRUE, :
arguments imply differing number of rows: 1, 9, 0, 14484
I am using below code to pull the data and convert it to data frame so that I can export the data using R.
library(jsonlite)
url = "https://www.quandl.com/api/v3/datasets/CHRIS/CME_S1.json"
data=jsonlite::fromJSON(url, simplifyDataFrame = TRUE)
data = plyr::ldply(data, rbind)
The data type is list :
str(data)
List of 1
$ dataset:List of 21
..$ id : int 10922651
..$ dataset_code : chr "CME_S1"
..$ database_code : chr "CHRIS"
..$ name : chr "Soybean Futures, Continuous Contract #1 (S1) (Front Month)"

..$ collapse : NULL
..$ order : NULL
..$ database_id : int 596
I can see that, this error is because the imported data is in the list format. Is there a way to convert it to data frame so that I can export it in any format? I tried different ways but did get success. I would appreciate any kind of help.
