Hello all, I am new to R, I am learning regression and logistic modeling with categorical predictor variables, when there is only one predictor categorical variable i can use as.numeric() but when more than two variable then what is solution? can anyone suggest me? Thanks vignesh [[alternative HTML version deleted]]

Hello folks, I am on learning phase of R. I have developed Regression Model over six predictor variables. while development, i found my all data are not very linear. So, may because of this the prediction of my model is not exact. Here is the summary of model : Call: lm(formula = y ~ x_1 + x_2 + x_3 + x_4 + x_5 + x_6) Residuals: Min 1Q Median 3Q Max -125.302

Hello, After development of recommendation engine with the R, before removal of outliers from data-set value of residual standard error was 1351 and after removal of outlier its 100. Still there is no accurate prediction which gives 10% correct(near) prediction. For more fitting i also have tried polynomial model with two ,three and four degree but still no improvement. Is there any most

Hola Mª Luz, Te cuento un poco mi visión: Lo primero de todo es tener claro qué quiero hacer exactamente en paralelo, se me ocurren 3 escenarios: (1) Aplicar un modelo en este caso SVM sobre unos datos muy grandes y por eso necesito hadoop/spark (2) Realizar muchos modelos SVM sobre datos pequeños (por ejemplo uno por usuario) y por eso necesito hadoop/spark para parelilizar estos procesos

As I found the memory problem with local machine/micro instance(amazon) for building SVM model in R on large dataset(2,01,478 rows with 11 variables), then I have migrated our micro instance to large instance at Amazon. Still I have memory issue with large amazon instance while developing R model for this dataset due to large size. I have attached the snap of error with local

Hi Experts, As i am a new in this forum, let me introduce myself:- i am Debaranjan, from India, Assam. I have heard many things about R and its statistical Magic feature. i am really have nothing knowledge about R language nor have ever used before. i am only a nursery in R. please help me in learning R. I have gone through many study material for R but have gain nothing

Hola, Puedes poner un RStudio en Amazon, poner "caret" y a correr.... No sé si tendrás suficiente con lo que te pueda ofrecer Amazon para tu problema... creo que sí... ;-).... O directamente hacerlo aquí, que toda esta instalación ya la tienen hecha: http://www.teraproc.com/front-page-posts/r-on-demand/ Gracias, Carlos.

Hi all, We use xapian as the backend of our system. Now the data need be indexed ever-increasing, and the local mode is hard to maintain, so we plan to move the index builder to hadoop. We try to make xapian can be run in hadoop, and now met a problem that there are many seek operations when xapian writes the index files, but the method seek() in hadoop c api only support read, and we blocked by

Hive <http://hadoop.apache.org/hive/> is a data warehouse infrastructure built on top of Hadoop that provides tools to enable easy data summarization, adhoc querying and analysis of large datasets data stored in Hadoop files. It provides a mechanism to put structure on this data and it also provides a simple query language called QL which is based on SQL and which enables users familiar with

Buenos días, alguien sabe si hay alguna manera de implementar una máquina de soporte vectorial (svm) con R-hadoop?? Mi interés es hacer procesamiento big data con svm. Se que en R, existen los paquetes {RtextTools} y {e1071} que permiten hacer svm. Pero no estoy segura de que el algoritmo sea paralelizable, es decir, que pueda correr en paralelo a través de la plataforma R-hadoop. Muchas

Dear R community, I find R fantastic and use R whenever I can for my data analytic needs. Certain data sets, however, are so large that other tools seem to be needed to pre-process data such that it can be brought into R for further analysis. Questions I have for the many expert contributors on this list are: 1. How do others handle situations of large data sets (gigabytes, terabytes)

Hi, I have trying to run a simple MR program using rmr2 in a single node Hadoop cluster. Here is the environment for the setup Ubuntu 12.04 (32 bit) R (Ubuntu comes with 2.14.1, so updated to 3.0.2) Installed the latest rmr2 and rhdfs from here<https://github.com/RevolutionAnalytics/RHadoop/wiki/Downloads>and the corresponding dependencies Hadoop 1.2.1 Now I am trying to run a simple MR

Hi all, Has anyone created a Xen cluster to run a hadoop vm cluster?

R-help group, I'm looking for some assistance on using an R-script to read STDIN from hadoop. Example, say I have two tables. One is a student table, the other is a class roster table (tables join on student_id). Student SAT score is in the student table, whether the student passed or not is in the roster table. So to determine if a student passed or failed based on their SAT score, I'd

Hola buenas, me preguntaba si alguno usa hadoop Spark en su día día y si me podíais recomendar un buen curso para empezar. Estuve en la charla de meetup de madrid hace unos meses de Rspark y estuvo bien, ahora me preguntaba si es posible profundizar. Pero me gustaría tener recomendaciones de cualquier material que podáis recomendar, cursos de coursera que hayais hecho, libros que hayais leido,

Hola, Quizás no es el ámbito más apropiado, pero vale la pena intentar. ¿Existe alguna implementación en R del modelo de reglas de asociación que pueda realizar el cálculo en paralelo sobre un cluster Hadoop? He visto los paquetes que 'paralelizan' R, pero no mencionan nada acerca de modelos de reglas de asociación. Saludos -- Oscar Benitez [[alternative HTML version deleted]]
