RJSONIO Installation
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

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).

conditional dependencies & loading
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?

Testing R packages on Solaris Studio
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:

Reading JSON files from R
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

plot(summary) within quantreg package
Quantreg package allows to plot the summary of models derived by quantile
regression at different taus.
The plot shows the parameters variation by varying taus: intercept and slope
(for a linear model).
Together with these values even confidence intervals may be plotted, based
on the threshold given within the summary (e.g. alpha=0.01 equals 99% CI).
However the graphic even plots the mean of

JDataFrame API
Hi Folks,
If you need to send data from Java to R you may consider using the
JDataFrame API -- which is used to convert data into JSON which then
can be converted into a data frame in R.
Here's the project page:
https://coherentlogic.com/middleware-development/jdataframe/
and here's a partial example which demonstrates what the API looks like:
String result = new JDataFrameBuilder()

Fast JSON <-> R converter?
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!

JDataFrame API
Hi Simon,
Thanks for your feedback. -- this is an observation that I wasn't
considering when I wrote this mainly because I am, in fact, working
with rather small data sets. BTW: There is code there, it's under the
bitbucket link -- here's the direct link if you'd still like to look
at it:

Extracting results from Google Search
Dear list,
I have a long list of towns in Africa and would need to get their
geographical coordinates. The Google query [/TownName Country coordinates/]
works for most of the TownNames I have and give a nicely formatted Google
output (try Ingall Niger coordinates for an example). I would like to launch
a loop on the list of names I have and automatically extract the coordinates
given by Google.

tools::package_dependencies problems
Hello, All:
tools::package_dependencies('Ecfun') failed to find how my
development version of Ecfun was using rJava, which generated errors in
"R CMD build Ecfun". This is because package_dependencies by default
uses CRAN and ignores locally installed packages.
What do you think about having this function check both locally
installed and CRAN versions?
