team_5: Team 5 Function
In yaweige/lab3group3: lab3group3

Description Usage Arguments Details Value Examples

Function based on the work by lab group 5 that converts a country shape file into a dataframe.

1	team_5(file, tolerance = 0.1)

`file`	This is the shape file that will be converted to a datafarme. It can either be a file path in the form of a character string (ends in .shp) or a sf shape file object created using the sf package with a geometry type of multipolygon.
`tolerance`	This controls how much the shape file is thinned. The larger it is made the less detail the shape file will have. The tolerance is set to 0.1 by default.

The variables included in the dataframe that is returned from team_5 are as follows.

country = country depicted by the data
group = indicates which polygon a set of points corresponds to
order = order in which the points in a polygon should be arranged
long = longitude of the point
lat = latitude of the point

A dataframe created from the shape file. See the details for the variables included in the dataframe.

# A shape file for Puerto Rico is already stored in the package
puerto_rico

# Use the team_5 function to convert the shape file to a dataframe
puerto_rico_df <- team_5(puerto_rico, 0.001)
head(puerto_rico_df)

# Create a plot of Puerto Rico using the dataframe
library(ggplot2)
ggplot(puerto_rico_df, aes(x = long, y = lat, group = group)) + geom_polygon()
