Aplicativos shiny

Si dejas correr este carrousel podrás ver unas capturas sobre cada uno de los aplicativos en los que he participado.

Manteniendo el ratón encima, aparece el título del aplicativo en la parte superior, y un menú para avanzar o retroceder más rápidamente.

Clica en la imagen si quieres utilizar el aplicativo (se abrirá en una pestaña nueva).

Shiny applications

This carrousel shows some snapshots from different applications in which I was directly involved.

The title of the application appears on top when the mouse cursor is positioned over the image, with a menu allowing to step back and forward faster.

Click on the image to try the app (a new tab will open).
