Dear R users, Any idea of how to calculate an area of an overlap between two functions? The only R build in function that I found is I Similarity Statistic for Quantifying Niche Overlap and I am really not sure if this function is producing exactly what I am interested in since I was plotting functions and often got confused results (for example: got high value for the overlap of one pair and low

Hello to everybody, I need to convert a json dataset in an R dataframe. I suppose that I'd need to use rjson or rjsonio package. The json dataset is: http://apistat.istat.it/?q=getdatajson&dataset=DCIS_POPSTRBIL&dim=1,0,0,0&lang=1&tr=&te= It would be nice if someone can help me to create a function like the one below:

Dear R-user, Could anybody tell me of the key difference between data mining and text mining? Please make a list for packages about data/text mining. And give me an example of text mining with R (any relating materials will be highly appreciated), because a vignette written by Ingo Feinerer seems too concise for me.

Hello, I would like to know if (as the usa map with Splus), it is possible with R to plot the french map and to add points (representing towns for instance) on the figure in the appropriate (x,y) system. Thank you. Nathalie Peyrard

After installation of R into VineLinux2.1.5, I started to enjoy statistics following some instruction, and found it very useful. One of my main purpose to use R is to try spatial statistics. Since library named "spatial" has already installed, I just tried ... > library(spatial) > towns <- ppinit(test.dat) ------- test.dat ------- x,y 4,7 5,7 5,8 5,9 6,7 6,8 6,9 7,8

Hello, I''ve looked around and I can't seem to find a package to do data mining in R for a mixture of categorical and numerical attributes. If you have this data set: ## dummy data set.seed(123) dummy <- data.frame(A = sample(paste("tasks",1:100), 10000,B = sample(paste("loads",1:100), 10000, replace = TRUE), B =

Dear R community, I’m new in R (coming from SAS). If possible, I’d like to know your thoughts regarding the following. I’m working on a regression problem, where my dependent variable is a ratio of two variables (i.e. dep.var=A/B). The variable A takes a value of zero for the vast majority of observations and, of course, so does the dependent variable. I thought I should do a weighted analysis

Version 2.4.0 of Rattle has been released to CRAN. The rattle package (http://rattle.togaware.com) is a multi platform (GNU/Linux, Mac/OSX, MS/Windows) GTK based GUI for data mining (for exploring data and building descriptive and predictive models). It has undergone a lot of development over the past year. A companion book introducing data mining using Rattle is under development, with a draft

Howdy Gurus I 'd like to ask a question about how to build TermDocMatrix in tm text mining package. It is not clear about importing a plain text file, and them converting that text file into TermDocMatrix file, etc to me. How can I build a TermDocMatrix of " a plain text document file for text association? Or are there any good manuals? Thank you in advance, -- Kum-Hoe Hwang, Ph.D.

Hello, I'm having issues working with the tm package on non-english languages. are there any extensions that enable the package to work with Hebrew (and other non-roman letter languages for that matter) ? (e.g. although I can construct a Corpus that shows the hebrew documents alright, I cannot create a term-document matrix (it does not identify any of the hebrew words, so it thinks there
