eq_create_label: Function to create popup_label text for interactive map

In RMHoek/NOAAearthquakeAnalysis: Data analysis of Significant Earthquake Data from the NOAA

Description

This function creates labels for an interactive map using three columns from a data.frame (the data variable). By default these are the "LOCATION" (the line_1 variable), "EQ_PRIMARY" (the line_2 variable) AND "TOTAL_DEATHS" (the line_3 variable) columns. It will omit all NA info from the label text, and returns a vector that can be used as popuptext column in the data.frame as label text in the eq_map function.

Usage

eq_create_label(data = NULL, line_1 = "LOCATION", line_2 = "EQ_PRIMARY",
  line_3 = "TOTAL_DEATHS")

Arguments

data	a data.frame containing columns named: "LOCATION" LOCATION info of earthquake events "EQ_PRIMARY" size of earthquake events on Richter scale "TOTAL_DEATHS" Total deaths info of earthquake events
line_1	the name of a column in data; by default "LOCATION"
line_2	the name of a column in data; by default "EQ_PRIMARY"
line_3	the name of a column in data; by default "TOTAL_DEATHS"

Value

character vector containing popup-text
