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 head. In short, I know that data() lists all of the available datasets, data("wines") will load the dataset wines, but how can I look at the raw data? I figure this is probably an easy question, but any help you can provide will be greatly appreciated. Thanks, Brock
Hi Brock, Have you tried View() ? Regards.

Try this: # each of these three show entire data set wines dput(wines) View(wines) # get help ?wines # various info on data set head(wines) tail(wines) summary(wines) str(wines) class(wines) dim(wines) # plotting plot(wines) # for a better plot see the example at the bottom of ?wines On Thu, Nov 26, 2009 at 11:46 PM, Brock Tibert <btibert3 at yahoo.com> wrote:> 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 head. > > In short, I know that data() lists all of the available datasets, data("wines") will load the dataset wines, but how can I look at the raw data? > > I figure this is probably an easy question, but any help you can provide will be greatly appreciated. > > Thanks, > > Brock > > ______________________________________________ > R-help at r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >
