applyTopOrIncAndNotExclFilter: Apply isTopOrIncAndNotExcl filter to a matrix

Description

Apply isTopOrIncAndNotExcl filter to a matrix

Usage

applyTopOrIncAndNotExclFilter(matrix, MARGIN, top = 1, falseValue = 0, ...)

Value

A matrix with the same dimnames but with elements not satisfying isTopOrIncAndNotExcl replaced by falseValue.

Arguments

matrix

A matrix.

MARGIN

Integer, 1 stands for row and 2 stands for column, passed to apply.

top

Integer, how many top elements should be kept, passed to isTopOrIncAndNotExcl.

falseValue

The same type as data in the matrix, used to replace values that is FALSE when judged by isTopOrIncAndNotExcl.

...

Further parameters passed to isTopOrIncAndNotExcl, including incFunc, excFunc, and decreasing. The function applies the filter function isTopOrIncAndNotExcl to each row or each column to a matrix, keeps the values that are TRUE based on the logical vector returned by function, and replaces the values that are FALSE with the value defined by falseValue.

Examples

myMat <- matrix(c(1,2,3,4,8,7,6,5,12,9,11,10), nrow=3, byrow=TRUE,
   dimnames=list(c("A", "B", "C"), c("Alpha", "Beta", "Gamma", "Delta")))
print(myMat)
applyTopOrIncAndNotExclFilter(myMat, 1, top=2, falseValue=-1)
applyTopOrIncAndNotExclFilter(myMat, 2, top=2, falseValue=-1)
applyTopOrIncAndNotExclFilter(myMat, 2, top=2, falseValue=-1, decreasing=FALSE)
applyTopOrIncAndNotExclFilter(myMat, 1, top=2, falseValue=-1, incFunc=function(x) x%%2==0)
applyTopOrIncAndNotExclFilter(myMat, 1, top=2, falseValue=-1,
   incFunc=function(x) x%%2==0, excFunc=function(x) x<5)
