Hi! I'm working on a package that must convert data to and from JSON. For this, it can use either the rjson package, or preferably, the faster RJSONIO package. I have two related questions about this. First, how can I specify that the package depends on *either* RJSONIO *or* rjson? (I.e. both are not required.) Second, what's the best-practice R idiom for such conditional loading?

I'm trying to install the rdatamarket package.

Hi All, has anyone run into maximum depth of nested JSON arrays in either rjson or RJSONIO ? I seem to be able to get up to 10 depth levels without problem, but crossing over to 11 either causes an error or fails to load the nodes properly. with RJSONIO I tried: a = fromJSON('data/myJSON.json', depth=1000) but I still get this error: Error in fromJSON(content, handler, default.size,

Hello to everybody, I need to convert a json dataset in an R dataframe. I suppose that I'd need to use rjson or rjsonio package.

Trying to install rjsonio and I've run into a couple of issues. 1. When installing from R, it's starts to download, then I get * installing *source* package 'RJSONIO' ... ERROR: configuration failed for package 'RJSONIO' * removing 'C:/Program Files/R/R-3.0.0/library/RJSONIO' 2. I've tried similar steps on the cmd(I'm win7). I receive the same message,

Is there a *fast* converter between JSON and R? I'm aware of the rjson package, but it is implemented in R, and it is too slow for my purposes. TIA! kynn [[alternative HTML version deleted]]

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

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

As most R developers maybe are already aware of, R version 1.2.0 introduced a new `generational' garbage collector which means that strings and vectors (and language objects) are handled differently from the numerical atomic types. >From ``Writing R Extensions'': Earlier code was written in a style like. VECTOR(dimnames)[0] = getAttrib(x, R_NamesSymbol);

I have setup a Solaris server to test packages before submitting to CRAN, in order to catch problems that might not reveal themselves on Fedora, Debian, OSX or Windows. The machine runs a Solaris 11.2 vm with Solaris Studio 12.3. I was able to compile current r-devel using the suggested environment variables from "R Installation and Administration" and: ./configure

Hi, I have tried to disable stack checking by set R_CStackLimit to -1. However, it always crashes my win32 multiple threads program. I am using R-2.5.0. My code looks like: #include <Rversion.h> #if (R_VERSION >= R_Version(2,3,0)) #define R_INTERFACE_PTRS 1 #define CSTACK_DEFNS 1 #include <Rinterface.h> #endif and then, add below line to my main function: R_CStackLimit =

Hello, I'm trying to use rjson to parse a JSON object. The object can be found here http://pastebin.com/np0s5hgM (you'll probably need to add quotes around the content) fromJSON returns the error glibc detected home/sguha/lib64/R/bin/exec/R: realloc(): invalid next size: 0x000000000209e210 *** Is there a fix coming soon?

First I tried 'setenv R_SHELL /usr/local/bin/bash', as bash is the weapon of choice for the faculty wishing to use R, then ran ./configure as before. The ./configure output line using as R_SHELL for scripts ... /usr/local/bin/bash would seem to indicate that the R_SHELL environment variable was recognized and acknowledged. However, I got the same build error: gnumake[2]: Entering
