getmax {MQMF}

getmax can be used to define the upper bound for a plot

Description

getmax generates an upper bound for a plot where it is unknown whether the maximum is greater than zero of not. If > 0 then multiplying by the default mult of 1.05 works well but if the outcome if < 0 then the multiplier needs to be adjusted appropriately so the maximum is slightly higher than the maximum of the data

Usage

getmax(x, mult = 1.05)

Arguments

x

the vector of data to be tested for its maximum

mult

the multiplier for both ends, defaults to 1.05 (=0.95 if < 0)

Value

a suitable upper bound for a plot if required

Examples

 vect <- rnorm(10,mean=0,sd=2)
 sort(vect,decreasing=TRUE)
 getmax(vect,mult=1.0)
 vect <- rnorm(10,mean = -5,sd = 1.5)
 sort(vect,decreasing=TRUE)
 getmax(vect,mult=1.0)
