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

...eControl(zipCmd=c("c:/programme/7-zip/7z a -tzip $$file$$","c:/programme/7-zip/7z x $$file$$ -aoa")) -> control where 'c:/programme/7-zip/' is the path to my 7-zip installation. You can then use control to set the control-parameter in odfWeave.

Hi All, This is probably basic, but I am just starting with R and very interested in learning how to automate my reports. I am just learning about Sweave and LaTex. I am following an example from online and am getting the following error: ....."Error unizipping file....unzip not found". I am not a programmer by any stretch, but I realize that the package is either not recognizing

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.

Hi Everyone, I am new to R and just trying my hand at plotting a network from my dataset. I am trying to teach myself network analysis, so this is probably an easy question. Using the package network, I have successfully plotted my network. I simply want to add labels to my vertices, with the label corresponding to the data I fed into the edgelist. For simplicity sake, my edgelist looks like

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, 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()
