👀¿Qué haces cuando ves un valor extremo en tus datos? ¿𝗟𝗼 𝗯𝗼𝗿𝗿𝗮𝘀? 🗑️
¡𝗔𝗹𝘁𝗼 𝗮𝗵í! ✋ Eliminar 𝗼𝘂𝘁𝗹𝗶𝗲𝗿𝘀 sin justificación es manipulación de datos.
Ese dato "raro" puede ser la clave de tu hallazgo, no un problema. 🛑 Investiga👇

En el Posgrado en Ciencia e Ingeniería en Computación de la @UNAM_MX se aceptaron 7 estudiantes de doctorado en el semestre que empezó en enero.
Normalmente todos tendrían beca.
@Secihti_Mx dijo que sólo darían beca a 4.
Estamos en abril y todavía no dan ninguna beca.

Looking to create stunning, data-rich maps in R? The tidyterra package makes it simple to integrate spatial data with ggplot2, bringing the power of the tidyverse to geospatial analysis. With tidyterra, you can work with spatial data just like any other data set in ggplot2.
✔️ Ease of Use: Simplifies map creation by integrating with ggplot2, using familiar functions and syntax, which reduces the complexity of working with spatial data.
✔️ Flexible Visualizations: Supports a variety of geospatial formats, allowing you to combine spatial data with other data sets, and work seamlessly with both raster and vector data.
✔️ Efficient Data Handling: Leverages dplyr-like functions for filtering, summarizing, and joining, which streamlines data processing and enables smooth integration between spatial and non-spatial data.
✔️ Beautiful Maps: Create detailed, customizable maps with less code and more flexibility, using the grammar of graphics you already know from ggplot2.
The visualizations shown here are taken from the package website and demonstrate how tidyterra simplifies creating detailed maps using ggplot2: dieghernan.github.io/tidyter…
If you’d like to learn more about ggplot2 and how to create stunning visualizations, check out my online course on “Data Visualization in R Using ggplot2 & Friends!” Learn more by visiting this link: statisticsglobe.com/online-c…
