R help - Jun 2015 - Spline Graphs

I wish to analyse longitudinal data and fit spline graphs to it looking to
the data pattern.

can someone suggest some starting point, and package in R to be used for
it.

what would be the requirement for structuring the raw data.

Hi,

That's not really enough information to help you. Why don't you do
some research on your own, and come back with a better-formulated
question?

A search at http://rseek.org/ for
spline longitudinal data
finds a lot of material that will help you get started.

Sorry if this appears twice but I am not sure the first attempt got through.

This is not much to go on but here is a short self contained example which
creates a longitudinal data frame L in long form from the built in data
frame BOD and then plots it as points and splines using lattice:

L <- rbind(cbind(Id = 1, BOD), cbind(Id = 2, BOD))
library(lattice)
xyplot(demand ~ Time | Id, L, type = c("p", "spline"))
