cor.pTs: Correlation of point with field

In EarthSystemDiagnostics/pfields: An R Package to Analyse Gridded Field Data

Description

Calculate the correlation between a point time series of class "pTs" and a field of class "pField" or "pTs", but also supports standard objects.

Usage

cor.pTs(point, field, debug = FALSE, ...)

Arguments

point	a "pTs" point object.
field	a "pField" or "pTs" field.
debug	point and field are brought onto the same time basis. If debug = TRUE, this new time basis is printed as a message.
...	further arguments passed on to the base R correlation function cor, such as the use argument.

Value

the correlation(s) between point and field. The class of the result depends on the class of field, so a "pField" or "pTs" object usually.

Examples

point <- rnorm(100)
field <- pField(rnorm(100 * 10 * 10), time = 1 : 100,
                lat = 1 : 10, lon = 1 : 10)

correlation <- cor.pTs(point, field)

pts.field <- field[, 1 : 25]
correlation <- cor.pTs(point, pts.field)
