telefit (version 1.0.3)

teleCor: Pointwise correlations for an exploratory teleconnection analysis

Description

Computes empirical correlations between rows of Y and Z, for use as exploratory analysis of teleconnection patterns between locations indexed by coords.s and coords.r. Optionally, an stData object containing Y and Z can be passed instead.

Usage

teleCor(
  stData = NULL,
  Y = stData$Y,
  Z = stData$Z,
  coords.s = stData$coords.s,
  coords.r = stData$coords.r
)

Arguments

stData

stData object containing data to analyze

Y

[ny x nt] a matrix composed of \(ny\) row vectors, each of which contains \(nt\) observations fom a different spatial location. Spatial locations for Y are indexed by coords.s.

Z

[nz x nt] a matrix composed of \(nz\) row vectors each of which contains \(nt\) observations from a different spatial location. Spatial locations for Z are indexed by coords.r.

coords.s

coordinates of locations in Y

coords.r

coordinates of locations in Z

Value

list with a matrix 'cor' containing correlations. The columns index remote coordinates, while the rows index the local coordinates. The returned list also includes the coordinates.

Examples

# NOT RUN {
data("coprecip")

cors = teleCor(coprecip)

# }
