read_nds: Read Nodes of a Decoration

In iconr: Graphical and Spatial Analysis for Prehistoric Iconography

Description

Read nodes' information from a file including all nodes and extract nodes of one decoration. Accepted formats are tab separated values ('tsv'), semicolon separated values ('csv'), or shapefile ('shp').

Usage

read_nds(site,
        decor,
        dir = getwd(),
        nodes = "nodes",
        format = "tsv")

Arguments

site	Name of the site
decor	Name of the decoration
dir	Path to the working folder, by default it is the working directory
nodes	Name of the nodes file (a dataframe or a shapefile)
format	File extension indicating a file format from 'tsv' (tab separated values), 'csv' (semicolon separated values) or 'shp' (shapefile). For 'tsv' and 'csv' the files must include node coordinates (nodes$x, nodes$y).

Value

Dataframe of graph nodes, including at least the columns "site", "decor", "id", "x", "y", with values for each node (row).

Examples

# Set data folder
dataDir <- system.file("extdata", package = "iconr")

# Read dataframe of nodes
nds.df <- read_nds(site = "Cerro Muriano", decor = "Cerro Muriano 1",
                    dir = dataDir, format = "tsv")
nds.df
## Dataframe of nodes

# Read shapefile of nodes
nds.df <- read_nds(site = "Cerro Muriano", decor = "Cerro Muriano 1",
                    dir = dataDir, format = "shp")
nds.df
## Dataframe of nodes
