geom_timeline: Module 2: Visualize the times at which earthquakes occur...

In vnmath/SoftwareDevinR: SoftwareDevinR Build Custom Geom ggplot element for describing mapping earthquakes

Description

Module 2: Visualize the times at which earthquakes occur within certain countries

Usage

geom_timeline(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE,
  ...
)

Arguments

mapping	Create asthetics mapping.
data	The data
stat	The statistical transformation as a string.
position	Position adjustment
na.rm	If 'FALSE', the default, missing values are removed with a warning. If 'TRUE', missing values are silently removed.
show.legend	show the legends or not
inherit.aes	the default aesthetics
...	Other arguments passed on to [layer()]. These are often aesthetics, used to set an aesthetic to a fixed value, like 'colour = "red"' or 'size = 3'. They may also be parameters to the paired geom/stat. #' @section Aesthetics: geom_timeline understands the following aesthetics x # Time variable y # Factor indicating some stratification color # Color of border of elements shape # Shape size # Size alpha # Transparency (1: opaque; 0: transparent) fill # Color of inside of elements stroke # Stroke

Details

The data to be used with this geom from NOAA website

Value

Produce a time line plot of selected earthquakes.

Examples

# The data must be cleaned using the function \code{eq_clean_data}, included in the package.
# Aesthetics can be specified in the \code{ggplot} function or in \code{geom_timeline} geom function
## Not run: 
data <- readr::read_delim("signif.txt", delim = "\t")
data <- eq_clean_data(data)
data %>%
dplyr::filter(COUNTRY == c("MEXICO","USA") & lubridate::year(DATE) >= 2010) %>%
ggplot(aes(x=DATE,y=COUNTRY,color=TOTAL_DEATHS,size=EQ_PRIMARY)) +
geom_timeline(alpha=.5) +
theme(legend.position="bottom", legend.box="horizontal", plot.title=element_text(hjust=0.5)) +
ggtitle("Earthquakes Visualization Tool") +
labs(size = "Richter scale value", color = "# deaths")

## End(Not run)
