Return function that finds maximum of its inputs within a clamping range — clampmax • nat

Return function that finds maximum of its inputs within a clamping range

clampmax(xmin, xmax, replace.infinite = NA_real_)

Arguments

xmin, xmax: clamping range. If xmax is missing xmin should be a vector of length 2.
replace.infinite: The value with which to replace non-finite values in the input vector. When codereplace.infinite=FALSE no action is taken. The default value of NA will result in e.g. Inf being mapped to NA.

Value

A function with signature f(x, ..., na.rm)

Details

Note that by default infinite values in the input vector are converted to NAs before the being compared with the clampmax range.

Examples

if (FALSE) {
LHMask=read.im3d(system.file('tests/testthat/testdata/nrrd/LHMask.nrrd',package='nat'))
d=unmask(rnorm(sum(LHMask),mean=5,sd=5),LHMask)
op=par(mfrow=c(1,2))
rval=image(projection(d,projfun=max))
image(projection(d,projfun=clampmax(0,10)),zlim=rval$zlim)
par(op)
}
