Hi Everyone, I was hoping someone could help me with the settings for Tinn-R. I see in the screen shots that it has syntax help, or something similar (tips on what functions, etc). I can not seem to get this to turn on in the program, and I am wondering if I have to set up a few options. I quickly read through the help and could not figure it out. Many thanks! - Brock P.S. It appears as

Hi All, I am making a serious effort to try to learn R, but one hurdle I am facing is that I need to "see" the data as I walk through the examples in the packages. For instance, many examples on the web start by a command like data("wines"). How can I actually view what the dataset looks like prior to transformations and analysis? I have tried to use edit() , print, and

Hi Everyone, I am relatively new to R, but I want to try to learn how to use it and potentially replace the other commercial packages I have learned to use over the years. That said, I need to get at data in databases, more specifically, MySQL. I installed the RMySQL package without error, but when I try to load it, I get the following error: > library(RMySQL) Loading required package: DBI

Hi All, I am still learning R, but making, IMO, great strides. I learned about Kohonen/Self-Organizing Maps in class and I would like to try to replicate some of the things we have seen in class. Below is my code. I am trying to create a u-matrix. In the documentation on page 9 it appears the type of plot, dist.neighbours should do the trick, however, I am getting an error: (Error in

Hi all, I am new to R, but with the help I have received thus,I have already been able to work through a bunch of questions on my own in just a few days. I imagine my questions are relatively simple, but here she goes. 1) I am using a package where one of the objects generated represents X/Y coordinates for each observation. I have been able to plot my row names onto the graph using text()

Hi everyone, I have successfully created and analyzed my network data. I am new to R, and Network Analysis too, but I want to color my vertex based on some of the centrality measures calculated. Can someone point me in the right direction? Again, I am new to R, but given how powerful R appears to be, I figure this is probably pretty easy to do, I just wish I could figure it out. Many thanks

Hi everyone, This is my first posting and I am just starting to fumble my way thru R. I have been working thru the Arules package, and I used to be able to use the image function and I get the following message: Error in image.default(basket2) : 'z' must be a matrix I used to be able to plot the image. I only started to get this error when I tried to add x and y axis labels.

Hi All, I am new to R, but it has been a lot of fun learning as I go and have been blow away by what it can do. Came across this example and wanted to see if ggplot2 or some other visualization package could make this sort of graphic.

The R package "pcalg" is released. The main purpose of this package is to estimate the skeleton of a DAG given data sampled from a distribution corresponding to this DAG. More intuitively, you can search for "strong dependencies" in potentially high dimensional data sets. The result will be an undirected graph where each edge represents some dependence statement. Optionally,

Hi, I've been using the package "graph" in the BioConductor assortment and writing some functions based on its classes. My question is not specific to this package or BioConductor (I think), but it serves as a useful example. I recently wanted to look at the code for the function "edgeMatrix" for the class "graphNEL". Usually I would type > func.foo and

Hola a tod@s, ayer mismo gracias a CarlosJ. Gil Bellosta me he enterado de la existencia de la lista R en España. Excelente idea!! Aprovecho este mensaje para comentaros un problema en la utilización del paquete psych y Rgraphviz que nunca había utilizado antes. Despues de cambiar a la versión R.2.8.2 y haberla reinstalado varias veces con vista. Cuando ejecuto test.psych() aparece un mensaje
