Point_map {PopGenHelpR}

A function to map statistics as colored points on a map.

Description

A function to map statistics as colored points on a map.

Usage

Point_map(
  dat,
  statistic,
  size = 3,
  breaks = NULL,
  col,
  out.col = NULL,
  Lat_buffer = 1,
  Long_buffer = 1,
  Latitude_col = NULL,
  Longitude_col = NULL
)

Arguments

dat

Data frame or character string that supplies the input data. If it is a character string, the file should be a csv. The first column should be the statistic to be plotted. The coordinates of each row should be indicated by columns named Longitude and Latitude. Alternatively, see the Longitude_col and Latitude_col arguments.

statistic

Character string. The statistic to be plotted.

size

Numeric. The size of the points to plot.

breaks

Numeric. The breaks used to generate the color ramp when plotting. Users should supply 3 values if custom breaks are desired.

col

Character vector indicating the colors you wish to use for plotting, three colors are allowed (low, mid, high). The first color will be the low color, the second the middle, the third the high.

out.col

Character. A color for outlining points on the map. There will be no visible outline if left as NULL.

Lat_buffer

Numeric. A buffer to customize visualization.

Long_buffer

Numeric. A buffer to customize visualization.

Latitude_col

Numeric. The number of the column indicating the latitude for each sample. If this is not null, PopGenHelpR will use this column instead of looking for the Latitude column.

Longitude_col

Numeric. The number of the column indicating the longitude for each sample. If this is not null, PopGenHelpR will use this column instead of looking for the Longitude column.

Value

A list containing maps and the data frames used to generate them.
