Intensity transformation for SPPs
Description
Intensity transformation for SPPs
Usage
transformIntensity(
spp,
method = "z-score",
irange = c(0, 1),
forceRange = TRUE
)
Arguments
spp:
a spatial point pattern of type 'ppp' with its 'marks' being a dataframe with
two columns 'idx'and 'intensity'.
method:
a character specifying the method of transformation, one of
'c("z-score", "sqrt", "scaling")' such that 'z-score' represents (analyte-wise)
standardization (subtraction of mean and division by std), 'sqrt' is the square
root transformation and 'scaling' is linear mapping of intensities into [0,1] range.
irange:
a numeric vector of two elements speciying the output range of
the scalled intensities.
forceRange:
logical, whether to force-map the intensities in to the range
given by 'irange' regardless of the 'method' used.
