subOrigData: subOrigData function

In SPATIAL-Lab/isorig: Rescale isoscape using known-origin tissue isotope values, and assign origin of unknown samples with isotopic data

Description

This function will permit subset the known-origin stable isotope dataset included in this package

Usage

subOrigData(taxon = NULL, group = NULL, mask = NULL)

Arguments

taxon	one string or a string vector. Select species names of known origin data. Details can be seen in knownOrig
group	one string or a string vector. Select group names of known origin data. Details can be seen in knownOrig
mask	SpatialPolygonsDataFrame. This mask will constrain the investigated area. If this is not provided, default of whole world is used.

Value

Data selected as SpatialPointsdataFrame from known-origin data from this package will be returned. It has one feature: d2H, which is ready to be fed into calRaster function.

Examples

## WITHOUT mask
# extract data of taxon of Jackdaw, Partridge and Willow Grouse
d1 = subOrigData(taxon = c("Danaus plexippus", "Setophaga ruticilla", "Turdus migratorius"))
summary(d1)

# extract data of group of [1]insect and [2]bird
d2 = subOrigData(group = c("insect","bird"))
summary(d2)

# extract data of group of human which only has hair
d3 = subOrigData(group = "human")
summary(d3)

# extract data of taxon of hair from human
d4 = subOrigData(taxon = "Homo sapiens")
summary(d4)

## WITH mask
d5 = subOrigData(taxon = "Turdus merula", mask = naMap) # No isotope data found in mask you choose!
d6 = subOrigData(taxon = c("Danaus plexippus", "Setophaga ruticilla", "Turdus migratorius"), mask = naMap)
d7 = subOrigData(group = "human", mask = naMap)
