arcsinetransform {doebioresearch}

Arc sine transformation of the numeric vector

Description

The function divide values by 100, does square root and than sin inverse of each values of vector. If any of the values of a vector is 0 or 100, it is replaced by 1/4n or 100-(1/4n), respectively.

Usage

arcsinetransform(numeric.vector, type, n)

Arguments

numeric.vector

data vector to be transformed

type

0 if data is in percentage and 1 if data is in proportion

n

is the number of units upon which the percentage/proportion data is based

Value

Arc sine transformed data

Examples

vector<-c(23,0,29.6,35.6,33,35.6,10.5,100)
# Arc sine trnasformation for percentage data and n=10
arcsinetransform(vector,0,10)
