cubicSpline0: Centile curves using cubic splines compared to noise data

In amouchot/nparamEstim: Nonparametric centile curves estimation

Description

Centile curves using cubic splines compared to noise data

Usage

cubicSpline0(x, y, cents = c(0.03, 0.25, 0.5, 0.75, 0.97), data)

Arguments

x	the explanatory variable - numeric
y	the response variable - numeric
cents	A numeric vector that represents the centiles calculated. Default is set to cents=c(0.03,0.25,0.5,0.75,0.97) )
data	the noise data to be compared to

Value

Plots centile curves with cubic splines and displays them on the same figure as the noise data

Examples

#create a sample data frame
sample<-data.frame(sample(30:42,50,rep=TRUE),sample(800:5000,50,rep=TRUE))
colnames(sample)<-c("Gestational Age in weeks","Weight in gramms")
x<-sample$`Gestational Age in weeks`
y<-sample$`Weight in gramms`
abnormal<-data.frame(sample(30:42,10,rep=TRUE),sample(800:5000,10,rep=TRUE))
colnames(abnormal)<-c("Gestational Age in weeks","Weight in gramms")
cubicSpline0(x,y,cents=c(0.03,0.25,0.5,0.75,0.97),data=abnormal)
