Hello dear Henser, You seem to be asking a homework question, which you will not get answers for here. In short, have a look at: ?read.table For reading the data. And: ?mean For the mean...
And go read through an introductory book on R. There is a long list here: http://www.r-project.org/doc/bib/R-books.html And another list here: (this link includes only freely available books) http://www.r-statistics.com/2009/10/free-statistics-e-books-for-download/ Cheers, Tal ----------------Contact Details:------------------------------------------------------- Contact me: [email protected] | 972-52-7275845 Read me: www.talgalili.com (Hebrew) | www.biostatistics.co.il (Hebrew) | www.r-statistics.com (English) ---------------------------------------------------------------------------------------------- On Thu, Dec 8, 2011 at 8:34 PM, Henser <[email protected]> wrote: > My problem is very easy, but it took me hours without a solution. > > So, I have to take any data set from UCI repository website for example > this > one which is about consensus income: > > http://archive.ics.uci.edu/ml/datasets/Census+Income > > And here is the data folder: > > http://archive.ics.uci.edu/ml/machine-learning-databases/adult/ > > My task is to caculate to do this: > a) Calculate measures of centrality (mean, median,...), dispersion (IQR, > standard > deviation...) and shape (skewness and kurtosis). > b) Make histograms, normal probability plots, bar plots, box-plots and stem > and leaf > plots. > c) Study the relation between, at least, two quantitative variables with a > linear > regression model. > > > The first big problem is: how to load the data base into R?
