View source: R/stheoreme.R

Description

Function utild2bin is applied to a pair of matrices and convert them to matrices of binaries with a rule specified by user

Usage

1
utild2bin(d2arr0, d2arr1, method = "mean", trsh = 0, inverted = FALSE)

Arguments

d2arr0

matrix to be binarized

d2arr1

matrix to be binarized

method

method of setting a threshold:

method='mean' threshold is mean(c(d2arr0, d2arr1)) for both matrices (used as default)

method='imean' setting individual thresholds as mean values

method='imed' setting individual thresholds as median values

method='i1stQ' setting individual thresholds as 1st quartile values

method='i3rdQ' setting individual thresholds as 3rd quartile values

method='isubsd' setting individual thresholds as (mean(d2arrN)-sd(d2arrN))

method='iaddsd' setting individual thresholds as (mean(d2arrN)+sd(d2arrN))

method='med' threshold is median(c(d2arr0, d2arr1)) for both

method='med0' threshold is median(c(d2arr0)) for both

method='med1' threshold is median(c(d2arr1)) for both

method='mean0' threshold is mean(c(d2arr0)) for both

method='mean1' threshold is mean(c(d2arr1)) for both

method='spec' threshold is specified by the 2 numbers of argument trsh individually for matrices

trsh

specifies the individual threshold values for binarizations when method='spec' is chosen. If it contains one number it will be interpreted as one threshold for both matrices

inverted

logical item specifying if the result will be inverted (zeros replaced by ones and ones replaced by zeros) after bianrization

Value

bin0

result of d2arr0 binarization

bin1

result of d2arr1 binarization

counts

summary/report of how the arrays were binarized
