In glottospace: Language Mapping and Geospatial Analysis of Linguistic and Cultural Data

Create static and dynamic maps from glottodata, or select languages from a map

Description

With this function you can easily create static and dynamic maps from glottodata (by setting type to 'static' or 'dynamic'). Alternatively, by specifying type = "filter", you can select languages by drawing/clicking on a map.

Usage

glottomap(
  glottodata = NULL,
  color = NULL,
  label = NULL,
  type = NULL,
  ptsize = NULL,
  alpha = NULL,
  lbsize = NULL,
  palette = NULL,
  rivers = FALSE,
  nclass = NULL,
  numcat = FALSE,
  filename = NULL,
  projection = NULL,
  mode = NULL,
  ...
)

Arguments

glottodata	Optional, user-provided glottodata. In case no glottodata is provided, you can pass arguments directly to glottofilter.
color	glottovar, column name, or column index to be used to color features (optional). Run glottovars() to see glottovars
label	glottovar, column name, or column index to be used to label features (optional). Run glottovars() to see glottovars
type	One of: "static", "dynamic", or "filter". Default is "static".
ptsize	Size of points between 0 and 1
alpha	Transparency of points between 0 (very transparent) and 1 (not transparent)
lbsize	Size of labels between 0 and 1
palette	Color palette, see glottocolpal("all") for possible options, and run glottocolpal("turbo") to see what it looks like (replace it with palette name). Alternatively, you could also run tmaptools::palette_explorer(), RColorBrewer::display.brewer.all(), ?viridisLite::viridis, or scales::show_col(viridisLite::viridis(n=20))
rivers	Do you want to plot rivers (only for static maps)?
nclass	Preferred number of classes (default is 5)
numcat	Do numbers represent categories? For example, if your dataset consists of 0 and 1, you might want to set this to TRUE.
filename	Optional filename if you want to save resulting map
projection	For static maps, you can choose one of the following: 'eqarea' (equal-area Eckert IV, default), 'pacific' (Pacific-centered), or any other Coordinate Reference System, specified using an EPSG code (https://epsg.io/).
mode	In case type = "filter", you can set mode to either "draw" or "click".
...	Additional parameters to glottofilter

Value

a map created from a glotto(sub)data object and can be saved with glottosave()

Examples

glottomap(country = "Netherlands")

glottopoints <- glottofilter(continent = "South America")
glottopols <- glottospace(glottopoints, method = "voronoi")
glottomap(glottodata = glottopols, color = "family_size_rank")
glottomap(glottodata = glottopols, color = "family", palette = "turbo",
type = "dynamic", label = "name")

glottodata <- glottoget()
families <- dplyr::count(glottodata, family, sort = TRUE)

# highlight 10 largest families:
glottodata <- glottospotlight(glottodata = glottodata, spotcol =
"family", spotlight = families$family[1:10], spotcontrast = "family", bgcontrast = "family")

# Or, place 10 largest families in background
glottodata <- glottospotlight(glottodata = glottodata, spotcol =
"family", spotlight = families$family[-c(1:10)], spotcontrast = "family", bgcontrast = "family")
glottomap(glottodata, color = "color")
