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]]

I'm trying to install the rdatamarket package. I did an install.packages('rdatamarket') command but got an error about half way through the install as follows: * installing *source* package ?RCurl? ... checking for curl-config... no Cannot find curl-config ERROR: configuration failed for package ?RCurl? The install continued after the error but looks like it was completed. I'm

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. The json dataset is: http://apistat.istat.it/?q=getdatajson&dataset=DCIS_POPSTRBIL&dim=1,0,0,0&lang=1&tr=&te= It would be nice if someone can help me to create a function like the one below:

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

Hello, I am trying to use RJSONIO I have: x <- c(0,4,8,9) y <- c(3,8,5,13) z <- cbind(x,y) Any idea how to convert z into the JSON format below? I want to get the following JSON output to put into a php file. [[0, 3], [4, 8], [8, 5], [9, 13]] Thank you.

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,

Hi friends, I was trying to install RJSONIO in Ubuntu10.04 LTS but unfortunately ends up with following error. trying URL 'http://stat.ethz.ch/CRAN/src/contrib/RJSONIO_0.98-1.tar.gz' Content type 'application/x-gzip' length 1150673 bytes (1.1 Mb) opened URL ================================================== downloaded 1.1 Mb * installing *source* package ‘RJSONIO’ ...

Hi Frederick, I described what I meant in the post I sent to R-help (https://stat.ethz.ch/pipermail/r-help/2016-September/442174.html), but in brief, by "zero overhead" I mean that the only thing needed for library code to be accessible to client code is for it to be located in designed directory. No additional meta-files, packaging/compiling, etc. are required. Best, G. On Sun, Oct

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,

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

Dear R People: I have been experimenting with rPython, rSymPy, and rJython.

I'm looking for a way to approximate the "zero-overhead" model of code reuse available in languages like Python, Perl, etc. I've described this idea in more detail, and the motivation for this question in an earlier post to R-help (https://stat.ethz.ch/pipermail/r-help/2016-September/442174.html). (One of the responses I got advised that I post my question here instead.) The

Hi Kynn, Thanks for expanding. I wrote a function like yours when I first started using R. It's basically the same up to your "new.env()" line, I don't do anything with environmentns. I just called my function "mysource" and it's essentially a "source with path". That allows me to find code I reuse in standard locations. I don't know why R does not

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?

Hi, everyone. I'm trying to debug an R-module, written in C, and I'm using gdb for this. How can I print "standard" R objects from within C code? BTW, I'm familiar with the advice to use R_PV given in Writing R Extensions, but it's not working for me. E.g., I get (gdb) p R_PV(x) $1 = void and yet (gdb) p *x $2 = {sxpinfo = {type = 16, obj = 0, named = 0, gp = 0,
