%0 Journal Article %T NOTE - Program R: applications in plant breeding %A Luiz Alexandre Peternelli %J Crop Breeding and Applied Biotechnology %D 2011 %I Brazilian Society of Plant Breeding %X Nowadays the demand for so-called free, or open source software for data analysis as well as the appeal to use it isgreat. An public domain software that has become extremely well-known, with ever-increasing numbers of fans and even coworkers, is Environment R, or simply R. R is extremely useful for data analysis and manipulation in view of a range of tools alreadyimplemented. Also, R is not simply a statistical program, because, by its easy on using internal functions and also creating new ones,statistical procedures applied to data can also be created, manipulated, evaluated and interpreted. R contains numerous libraries(or packages), some already included in the default setting. This course will focus on the application of R in statistical analyses inplant breeding. Explanations on the use of various commands and functions will be illustrated with examples, to facilitate theinterpretation and adaptation to other similar problems. %K statistical analysis %K design of experiments %K data analysis. %U http://www.sbmp.org.br/cbab/siscbab/uploads/c8eb9792-5a2b-2309.pdf
