Interacción entre excel y el lenguaje R, una aplicación en biología pesquera

In this paper we present the basic methodology to use the mathematical - statistical package R and its programming language, from an Excel spreadsheet. An example is presented in which, from the length data from a sampling of the catch of a certain fishery, the descriptive statistics and the corresponding histogram are obtained. The size distribution is calculated in later times, using the Von Bertalanffy growth equation and the natural mortality curve. Finally, using the weight - length relationship, an estimate of the biomass is made. Keywords:  Spreadsheet, Excel, R Language, Population Dynamics, Fisheries .
