I have a few stand-bys such as the mtcars and CO2 data sets in the base packages of R but sometimes I need a long format data set or a bunch of categorical or a bunch of numeric or repeated measures or I want it to have missing values to test the function and I spend valuable time searching for the correct data set. About a year ago my answer was to have a file with several data sets I knew

**Using multiple regression model from training set to**

To build logical vectors in R, you’d better know how to compare values, and R contains a set of operators that you can use for this purpose. Operator Result x == y Returns TRUE if x exactly equals y x != y Returns TRUE if x differs from y x > y Returns TRUE if […] how to order a holden key 2004 Creating R Packages: A Tutorial Friedrich Leisch Department of Statistics, Ludwig-Maximilians-Universit at Munc hen, and R Development Core Team, Friedrich.Leisch@R-project.org September 14, 2009 This is a reprint of an article that has appeared in: Paula Brito, editor, Compstat 2008-Proceedings in Computational Statistics.

- We use normality tests when we want to understand whether a given sample set of continuous (variable) data could have come from the Gaussian distribution (also called the normal distribution). Normality tests are a form of hypothesis test, which is used to make an inference about the population from which we have collected a sample […]
