Description

The function takes an argument eq_data containing the filtered data frame with earthquakes to visualize. The function maps the epicenters (LATITUDE/LONGITUDE) and annotates each point with in pop up window containing annotation data stored in a column of the data frame. The user is able to choose which column to use for the annotation in the pop-up with a function argument named annot_col. Each earthquake is shown with a circle whose radius is proportional to the earthquake's magnitude.

Usage

eq_map(eq_data, annot_col)

Arguments

eq_data	A data frame containing earthquake related data.
annot_col	The column name which should be used for annotation purpose

library(dplyr)

  eq_clean_data() %>%
  dplyr::filter(COUNTRY == "CHINA" & lubridate::year(DATE) >= 2000) %>%
  eq_map(annot_col = "DATE")
