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.
Examples
# \donttest{
data(Het_dat)
Test <- Point_map(Het_dat, statistic = "Heterozygosity")# }
