1. Introduction {#intro}

I have decided to create a new theme because it is a good opportunity to doing it so I have used the default theme and I have changed some visuals. As you can see, I have made a great effort to make it be similar to the example posted in class notebooks.

2. Example {#example}

Adding theme to a regular plotting of earthquake.

Without theme:

# Path to the raw data.
raw_data_path <- system.file("extdata", "signif.txt", package = "msdr")
# Loading the dataset of Earthquake.
df <- readr::read_delim(file = raw_data_path,      
                        delim = '\t',              
                        col_names = TRUE,          
                        progress = FALSE,           
                        col_types = readr::cols())
# Cleaning the data and filtering.
df %>% 
       eq_clean_data() %>%

              filter(COUNTRY %in% 'USA',
                     YEAR >= 1900 &
                     YEAR <= 2000) %>%
              # Creating a ggplot object
              ggplot() + 
                     # Using the new Geom
                     geom_timeline(aes(x     = DATE,
                                       y     = COUNTRY,
                                       size  = EQ_PRIMARY,
                                       color = TOTAL_DEATHS)) -> earthquake_usa_1900_2000
# Plotting
earthquake_usa_1900_2000

Adding theme:

# Adding theme.
earthquake_usa_1900_2000 + theme_msdr()
