similar to: SQL query with Multicore option on R -linux

Hi all, I have R installed on a box, which is running on a machine with 16 core and Redhat - Linux. I am handling huge (size of dataset will be 5 GB) dataset. Lets assume that my data is in the form of structured (multiple) logs. I access the data by using all.files(). Since by default basic version of R utilizes single core, the processing of my analysis code is taking too much time. I got to

Hi all, I have multiple data frames created with equal number of columns in each data frame by using mclapply() on multicore processor. The data frames are like DF[[1]], DF[[2]], ... DF[[150]]. Now i want to bind (Similar like rbind()) all these data frames and create one single data frame called DF so that i can have the complete data for further analysis. Can someone help me in performing this

Hi All, I want to join a table (Dataset) that is created in R with a table that is in oracle database. Can some one help me in accomplishing this task in R?

Hi, I have requirement to move the data from Linux local path( ex /home/user/sample.txt) to hadoop HDFS using RODBC in R I knew that we can move the data using rhive comamnds like *rhive.put* and *rhive.get *but looking for similar commands using RODBC as well. I would appreciate for your inputs. Regards, Divakar Phoenix, USA [[alternative HTML version deleted]]

Hi, I am looking for a way to generate a matrix of random numbers in a way that each row of the matrix would sum to 1 and that the numbers in the columns of the matrix would have a uniform distribution. So far I have found several ways to create random numbers that would sum to 1, but then the distribution of the individual elements is more or less skewed - there are much more small numbers than

i connected Rserver successfully. can do some functions like rnorm(),print(),etc... i am connecting R with Hive-hadoop i have installed library "RHive" which will take care of connection but when i am connecting it throws warning..like "Warning: type 7 is currently not implemented in the PHP client." code:-->

This patch adds byte run reporters for node and value metadata in the hivexml program. Each byte run represents the offset and length of a data structure within the hive, one per node, and one or two per value depending on the length of the value data. In order to add this metadata reporting, the following changes were put in place: * Split value_key function into value_key and value_key_len. *

Hello All, I suspect I am having a problem with my R installation, something that has to do with "--enable-R-shlib". Can someone explain if this is something that I can fix using apt-get? More specifically: I am having trouble getting installing the RHive package. I Installed R from scratch, following the instructions in (for example): http://cran.ru.ac.za/bin/linux/ubuntu/

Hi, When an integer argument is passed as value, node_set_value segfaults. Reproducer is at the end of this message The backtrace points at hivex-py.c, function get_value. While obj is non-NULL, `bytes = PyUnicode_AsUTF8String (obj);` returns NULL. Kind regards, Peter https://lekensteyn.nl #!/usr/bin/env python3 import hivex, sys h = hivex.Hivex(sys.argv[1]) print(h) val = {

Hi, This patch series is based on a prior patch[1], splitting off changes as requested and incorporating feedback from Richard Jones. It introduces type validation to avoid segmentation faults (instead, it reports an exception) and fixes handling of the bytes type in Python 3. Major changes since that series: - Drop newly introduced support for integer types for DWORD/QWORDS - Reject Unicode

Hi Friends, Kindly let me know whether is it possible to install R project in a Server (Remote) desktop, which can be accessed by many users by logging in with their credentials...

Several years ago there were R implementations of a socio-linguistics analysis method called Variable Rule Analysis namely rbrul and r-varb. Both neither of the sites listed (in the method's WikiPedia page http://en.wikipedia.org/wiki/Variable_rules_analysis ) appear to be online any more (one was at UPenn and the other at Indiana). Does anyone know a) whether the code for either or both of

Thanks - Peter, Eivind, Rui Sorry, I perhaps could not explain it properly in the first go. Trying to simplify it here with an example - Say I have two dataframes as below that are NOT equally-sized data frames (i.e., number of columns are different in each table): Table_A: Email Name Phone abc at gmail.com John Chan 0909 bcd at yahoo.com Tim Ma
