glottomap {glottospace}

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")
