Tanto terra::aggregate() como mean() devuelven un objeto SpatRaster. terra::aggregate() crea un objeto SpatRaster con menor resolución (celdas más grandes) y mantiene el objeto con la misma cantidad de capas, este agrega áreas rectangulares para crear celdas más grandes. Mientras que mean() calcula estadísticas de resumen para celdas, ya sea entre capas o entre capas (resumen paralelo), lo que significa que la función media da como resultado un objeto SpatRaster con una capa que tiene la misma cantidad de celdas y no cambia la resolución. A continuación se muestra la Tabla 1, que muestra los valores de resolución y dimensiones antes y después de utilizar las funciones mencionadas.

Your revised text is much clearer, but there are still a couple of minor grammar issues. Here's a further refinement:

"Both terra::aggregate() and mean() return a SpatRaster object. terra::aggregate() creates a SpatRaster object with lower resolution (larger cells) while keeping the object with the same number of layers. It aggregates groups of rectangular areas to create larger cells. On the other hand, mean() computes summary statistics for cells, either across layers or between layers (parallel summary). This means that the mean function results in a SpatRaster object with one layer that has the same number of cells and does not change the resolution. Below is Table 1, which shows the values of resolution and dimensions before and after using these functions."

In this revision:

I added "On the other hand" to introduce the contrast between aggregate() and mean() more explicitly.
I separated the explanations of aggregate() and mean() into two distinct sentences for clarity.
I used "these functions" to refer to both aggregate() and mean() to avoid repetition.
These changes make the text more concise and easier to follow.<end_of_turn><eos>
