Data processing in physics with open source program R
Abstract. R is an open-source statistical environments modeled after S language. R has many function for statistical analyses and graphics. The results from a statistical analyses are displayed on the screen, some intermediate results can be saved, written in a file, or used in subsequent analyses. R could seem too complex for a~non-specialist. This may not be true actually, a main feature of R it's flexibility. Classical software displays immediately the results of an analysis, R stores these results in an ”object“, so that an analysis can be done with no result displayed. We will see some examples of statistical models for analysis the data from an physics experiment illustrating the flexibility of a system such as R. This contribution covers several topics in data analysis, including curve fitting and presentation of the results of analysis by LaTeX typographical system. R is freely distributed under the terms of the GNU GPL licence.
Key words and phrases. Regression, data processing, open source, R.
