Dear all, I'm looking for some material on data mining with R. I have something from Luis Torgo but I'd like to see something else. If anybody could help me I'll be thankful Adri??n

Howdy! Could somebody point me to some good introductory readings about data mining and descriptive data analysis? I'm a psychologist and a couple of times I realized that some things just don't appear in psychological literature, e.g. I've never seen a box plot anywhere in psych journals so I'm not familiar with them. The R help function is great when it comes to explaining

Dear R users, I have been trying to use RQuantLib in the 2.12.2 R version. I downloaded the .zip file from <http://sourceforge.net/projects/quantlib/files/QuantLib/> http://sourceforge.net/projects/quantlib/files/QuantLib/ which didn't work, so I I downloaded the package source from <http://sourceforge.net/projects/quantlib/files/QuantLib/1.0.1/>

I have been RTFM/doc/www, but I'm still lost. How does one tell R CMD INSTALL and R CMD check (both) that libraries are installed in non-usual places and so -I/APPS/include (or whatever) is necessary in CPPFLAGS and -L/APPS/lib (similarly) is necessary in LDFLAGS? I know I can hardwire them in pkg/src/Makevars, but this requires hand editing of that file by each installer (yuck!) rgentlem

Hi, how can I import really big plain text data files (several GB) from an ERP-System (SAP-Tables) to R? The Header of these files are always similar, for example: Tabelle: T009 Angezeigte Felder: 7 von 7 Feststehende F??hrungsspalten: 2 Listbreite 0250 ---------------------------------------------------------------------- |X|MANDT|PERIV|XKALE|XJABH|ANZBP|ANZSP|LTEXT

Hello all, I am currently working with rpart to classify vegetation types by spectral characteristics, and am comming up with poor classifications based on the fact that I have some vegetation types that have only 15 observations, while others have over 100. I have attempted to supply prior weights to the dataset, though this does not improve the classification greatly. Could anyone supply some

Dear R-user, I wish to know if someone is using R as concern Datamining or KDD (Knowledge Discovery in Database) and if already exists a R package specialized in this kind of analysis. I found this contributes on the R web site: [20] Diego Kuonen. Introduction au data mining avec R : vers la reconqu??te du `knowledge discovery in databases' par les statisticiens. Bulletin of the Swiss

Deall all, We need to perform a statistical analysis of a large database (40,000 entries with approximately 500 fields in each entry) currently handled in Oracle. The data contains categorical variables only. At the current stage we suggest classification and clustering analysis. We are planning to perform the analysis in R and would be very grateful for any

Joshua, Thanks for the response. When you said at least version 3.4.0, I upgraded to 3.4.2 which I believe is the current version. Now, I attempted to install the package RQuantLib but it did not work. Here is what I got: > install.packages("RQuantLib") Installing package into ?C:/Users/rsher/Documents/R/win-library/3.4? (as ?lib? is unspecified) Warning message: package

OA, Thanks for the response. I downloaded the file RQuantLib_0.4.4.tar.gz into a directory c:\r.zip on my Windows machine. I then ran the following command and I received the following output: > install.packages("RQuantLib", lib="/r.zip/") Warning message: package ?RQuantLib? is not available (for R version 3.4.3) I did not unpack the .gz file. Should I have? Please

I have recently installed R on my new computer. I also want to install the package RQuantLib. So I run the following command and get the following output: > install.packages("RQuantLib") Installing package into ?C:/Users/rsher/Documents/R/win-library/3.2?

I was wondering if R had a data mining componant and how i could get it.

Hi All, I am in the process of writing an R extension in c++ and am using several STL containers (e.g., vector<double>, map<int, double>, multimap<int, double>). I make sure to clear all these containers at the end of the .Call. Everything compiles and runs just fine, but I'm a bit worried since I haven't found any other packages that use STL. So, my question: is it

Sometimes that message appears when using a CRAN mirror that is not up-to-date or has communication problems. Might also try another mirror. -- Sent from my phone. Please excuse my brevity.

Hi everybody, i'm working on the next version of the CreditMetrics package. So i have the question, are there any functions or packages which have have the functionality to calculate dates with a certain day count convention like act/360 or 30/360? Intensive search in the r-help archive or in the manuals did not bring any solution. thanks everybody for some help. best regards Andreas
