Get and prepare curve

Description

load a curve of interest

Usage

get_curve(curve = NULL, verbose = FALSE)

Arguments

curve	SpatRaster. Curve value, vector, grid or list of grids indicating the relative altitude of a biogeographic system per time period compared to the present. A typical example is a sea level curve indicating the relative sea level position above or below sea level compared to the present.
verbose	Boolean. FALSE: No messages are printed. TRUE: Standard verbose mode. 2: Very verbose mode, displaying detailed information.

Value

A SpatRaster or vector with curve values in a suitable format for the reconstruct function.

Examples

curve <- get_curve('lambeck')
curve <- get_curve('cutler')
curve <- get_curve('IPCC')
curve <- get_curve('funza')

curve <- get_curve()
curve <- get_curve(10)
curve <- get_curve(c(0,100,200,300,400,500))

# period definition curve 
cur <- c(0,100,200,300,400,500) # altitudes
names(cur) <- c(0,1,2,3,4,5) # periods 
curve <- get_curve(cur)

# add source attribute
cur <- c(0,100,200,300,400,500) # altitudes
names(cur) <- c(0,1,2,3,4,5) # periods 
attr(cur, 'source') <- 'new curve' # curve source 
curve <- get_curve(cur) 

# custom-curve from data frame
cur <- data.frame(period=0:10, 
                  altitude=seq(0,-20,-2), 
                  source='custom')
curve <- get_curve(cur)
