Usage

eq_create_label(data)

Arguments

data	The quakes data frame.

Details

This function creates a vector of HTML-formatted labels using supplied quakes data. The function creates lines of the format Label: value from the following variables in the quakes data set:

library(dplyr); library(lubridate)
## Create a popup_text variable and use that for the label
quakes <- eq_load_clean_data() %>%
 dplyr::filter(COUNTRY == 'JAPAN') %>%
 dplyr::filter(lubridate::year(DATE) >= 2000) %>%
 dplyr::mutate(popup_text = eq_create_label(.))
eq_map(quakes, annot_col = 'popup_text')
