I am trying to get the RJDBC and rJava .5to work on both my windows xp

R and Hadoop Integrated Processing Environment - RHIPE
Hello,
We have created an interface between R and Hadoop so that the user
can, after a fashion, interact with very large datasets
using the Map Reduce programming model. We also use IBM's TSpaces to
implement a shared memory implementation that can be
accessed via R(somewhat like networkspaces). RHIPE uses Rserve to
execute R code.
Some of the functions implemented are:

Hadoop Hive output read into R
All,
I am using a pretty crude method to get data out of HDFS via Hive and into R and was curious about alternatives that the group has explored.
Basically, I run a system command that runs a hive statement and writes the returned data to a delimited file. Then, I read that file into an object and continue.
For example:
hive.script <- "select * from orders where date =

Regarding your distributed text mining with tm
Hello,
I had been using R for text mining already. I wanted to use R for large
scale text processing and for experiments with topic modeling. I started
reading tutorials and working on some of those. I will now put down my
understanding of each of the tools:
1) R text mining toolbox: Meant for local (client side) text processing and
it uses the XML library
2) Hive: Hadoop interative, provides the

RJava question(class not found with rJava's vm, though found with alternate vm)
Not sure if this the right place, but I can't seem to subscribe to the rJava
mailing list. Sorry for the noise.
I have a jar file in the CLASSPATH variable. On running .jinit and checking
.jclassPath, i can see the jar file containing the class. Yet when trying to
instantaite the class, i get a class not found error.
Now If if, create my own vm (see below), and then run .jinit (which will

R CMD build errors if files cannot be moved, even if they are in Rbuildignore
When a package is built it is first moved to a temporary directory (lines
962-980 in build.R). However, this moves *all* files to the temporary
directory, even those in Rbuildignore; only later (lines 997-1024) are
Rbuildignore files excluded.
The problem with this approach is that some files in the package directory
may not be movable. On Windows at least, the full path name to a file must

semi-OT: t-bird mime type on .pdf attachment is wrong
I was sending my manager a copy of a form, and attached it (not inline),
using -t-bird, and he complains it didn't want to open. Looking at the
message source, t-bird had decided that the mime type was all/allfiles,
though the name ended in .pdf. I've searched via the config editor, and
I've been googling, and not finding anything. (I just *adore* the current

I have a function 'ewrap' (see below for definition).
It takes 3 expressions and returns another expression e.g.
