center.fsd.fd: Compute the centered version of spatial functional data
Description Usage Arguments Value See Also Examples
Description
This function is used to center spatial functional data.
Usage
1 | center.fsd.fd(X, margins = NULL, na.rm = FALSE)
|
Arguments
X |
the functional spatial data. |
margins |
the margins for which the centering should be done separately in every entry, in order to remove a trend. |
na.rm |
whether or not missing values should be ignored. |
Value
the centered data.

Examples
1 2 3 4 5 6 7 8 9 10 11 12 13 | data("temp")
# blindly center the data
T.centered = center.fsd.fd(temp)
# there is a clear structure in the empirical means
plot(mean(T.centered, margins = 1:2))
# take the latitude and the longitude as baseline
T.centered2 = center.fsd.fd(temp, margins = 1:2)
# random noise in the empirical means
plot(mean(T.centered2, margins = 1:2))
# this is the baseline
plot(mean(temp, margins = 1:2))
