The paper describes types and features of open software distributed under the open license, what gives users free possibility to use and modify. Types and examples of software devoted to universal management Systems as well as to address special user needs are presented. The author describes benefits of using open software in economy and public administration. The result of the analysis is presented: what are the main reasons that there can be observed still too small application of open software in companies and institutions. The author shows propositions of main activities to change this state as well.

This article is intended to be a position paper on advantages of free and open software for statistics and its applications to biometrics and biostatistics. Especially, the authors focus on the R package viewed as a new and still insufficiently recognized or received by the scientists, researchers, students, etc. Sample statistical computations and tests in biometrics are presented, and the most common functions and procedures are analysed and compared. Although this is a position paper from the point of view of applied computer science, the authors briefly present some original results within applied statistics (in particular: biometrics) and related computational methods using dedicated software.
