similar to: Importing JSON Hash Table

I have come across an issue converting a JSON string in R (with either the package 'rjson' or 'RJSONIO') when big integers are included in the JSON string. A simple example of the problem is: > options(scipen=999) # To prevent representing the answer in scientific notation > json.str <- '{"bigInt":123456789123456789}' # Sample JSON string with big

Hello All - I am trying to use RJSONIO to read in some JSON files. I was wondering if anyone could please comment on the level of complexity of the files it can be used to read, exports from or directly from NoSQL DBMS like MongoDB and such. Also, i understand that in reading the JSON file RJSONIO will automatically create the necessary structures. However I cannot seem to use to to read the

Regarding the question: From the linux shell I use the "-k" switch with cURL to ignore cert errors.. is there an equivalent in the R world? I have (sometimes) had success by creating a .curlrc file and putting the necessary curl options in it. When R invokes curl, curl picks up the options. [my context was running install.packages( method='curl' ) pointing to a local

[non-tabular json data] -- ok.. so I think I need to figure out how to make it tabular. Thanks! [curl] -- I was hoping there was a cleaner way to do it.. using R to evoke cURL to get the data as text and then passing it into getJSON seems to be what I need to do. Do you by chance have an simple example of using RCurl to get a response ignoring cert errors? ty -Rich -----Original Message-----

Hi Rich, Take a look at the function fromJSON found in the rjson package. Note that the Usage in the help page: ?fromJSON names the second argument 'file' but if you look at the description the argument can be a URL.

That said, I have two issues to ask for help with: 1) how to ignore cert errors with a fromJSON call And 2) why the json data from the example link doesn't convert to a data frame. As seen in the following example library("rjson") result <- fromJSON(file =

Hi, I am trying to consume a web service that returns a JSON string, however, when I run > fromJSON(s) Error: '\/' is an unrecognized escape in character string starting "http:\/" because the string s contains a single backslash, which is the JSON escape character, but R expects 2 backslashes, I think. Is there anyway to preprocess the JSON string returned from the web

Hi David, .. I think I've got it :-) Please let me know if you see anything glaringly wrong with this: library(RCurl) zWebObj <- postForm("https://www.semantic-mediawiki.org/w/api.php", "action" = "ask", "query" = "[[Category:City]]|?Capital%20of|?Has%20area", "format" = "json" .opts = list(ssl.verifypeer =

I'm trying to read two data sets in json format from a single .js file. I've tried fromJSON() in both RJSONIOIO and RJSON packages, but they require that the lines be pre-parsed somehow in ways I don't understand.

Right. I'm trying to access a server within my organization which has a cert error that I cannot fix. The example link I provided was to a site on the web that does not have the cert error. From the linux shell I use the "-k" switch with cURL to ignore cert errors.. is there an equivalent in the R world? -Rich -----Original Message----- From: David Winsemius [mailto:dwinsemius

Hola comunidad eRrera, Acudo a ustedes después de pelearme un rato y salir perdedor con la lectura de un archivo json. Por el momento he conseguido leerlo y transformar la parte que me interesa a data frame, sin embargo no consigo poder manipular los datos para calcular por ejemplo la media de una de las variables. El código que estoy ejecutando es: library(jsonlite) json_data <-

People, I didn''t get an answer to this before so I am trying again: I could change an existing "policy" table to "policies" with no drama but the are a number of related tables ie: p_2quot p_addr p_cc p_cs p_direct p_div p_exss

People, I am using: before_filter :login_required in my Controllers and this works fine. For some tables I am happy to use the output of eg: ruby script/generate scaffold Author but is there some way that I can disable Create, Edit, Destroy for some user logins in the corresponding view?

People, I have an insurance company client and for the last eleven years I have wanted to completely redevelop their system from scratch. However, the boss has never been interested in hiring a team to develop the new system (partly because of the cost and partly because of some famous and expensive development failures in the industry) and has always insisted on incremental development of the

People, I want to create seven plots on the one graph - each with it's own Y axis and scale - I want the plots overlaid because it is the shape of the graphs that I want to compare, not so much the values. I have found examples where people show how to put two Y axes on the left of the plot but I couldn't find examples of any more than that - is it possible? Thanks, Phil. --
