  plotOC(time = 1:nrow(curves), curves, xlab = "time",
    ylab = "value", main = "Original curves")

Arguments

time

a vector containing the observation time for the curves. If absent the time param will be set at the vector 1:nrow(curves)

curves

the observations matrix. Each column of this matrix corresponds to one observed curve, and contains the value of the curve at discrete time points.

xlab

label of the horizontal axis

ylab

label of the vertical axis

main
