Mi primer raster.Rmd

hoy aprendimos a crear un raster de juguete, le añadimos algunos valores y lo ploteamos; generamos nuestro cuaderno para ser publicado

This is an R Markdown Notebook. When you execute code within the notebook, the results appear beneath the code.

Add a new chunk by clicking the Insert Chunk button on the toolbar or by pressing Ctrl+Alt+I.

When you save the notebook, an HTML file containing the code and output will be saved alongside it (click the Preview button or press Ctrl+Shift+K to preview the HTML file).

The preview shows you a rendered HTML copy of the contents of the editor. Consequently, unlike Knit, Preview does not run any R code chunks. Instead, the output of the chunk when it was last run in the editor is displayed.
