Piecewise redundancy analysis (pwRDA)

Perform a pwRDA using the specified breakpoints

pwRDA(x.ord, y.ord, BPs, n.rand = 99)

Arguments

• x.ord: ordered explanatory matrix
• y.ord: ordered community matrix
• BPs: community breakpoints
• n.rand: The number of randomizations for significance computation

Returns

Returns an invisible list of length 4:

1. ..$summ: summary statistics of the pwRDA analysis;
2. ..$rda.0: full model cca object, which is described separately in vegan::cca.object
3. ..$rda.pw: pw model cca object, which is described separately in vegan::cca.object

Examples

data(sim1)
sim1o<-OrdData(sim1$envi,sim1$comm)

w50<-SMW(sim1o$yo, ws=50)
sim1.pw<-pwRDA(sim1o$xo,sim1o$yo, BPs=bp(extract(w50)))
