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:

• DATE

• LOCATION_NAME (as cleaned in the eq_location_clean function).

• EQ_PRIMARY (earthquake magnitude)

• TOTAL_DEATHS

Any of the above variables with missing/NA values are skipped in the label.

Value

Examples

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')
