R help - Nov 2007 - centile reference chart / clildren growth chart - what package/method to use

We are constructing growth charts (age/weight and age/length) for children
with diagnosis that impacts weight/length. 

But we we don't know how to use R for producing growth charts. 

We are collection data of Age, Weight and Length.
The data are used to produce diagnosis-specific Growth charts (like the CDC
Growth Charts:
http://www.cdc.gov/nchs/data/nhanes/growthcharts/set1clinical/cj41l017.pdf)

Data-example is in the UsingR package as data(kid.weights).

In the CDC-papers a LMS approch is described. Cole has programmed the
methology (I guess) in a <R 2.0.0 package called lmsqreg:
"""
> library(lmsqreg)
Error in library(lmsqreg) : 
lmsqreg' is not a valid package -- installed < 2.0.0?)
"""

Where to go forward in R.
Thanks for any "hints". 
We are using R2.6.0 on win/linux

The lmsqreg package is by Vince Carey and is available from his
website.  There is an independent package with fortran routines from  
Tim Cole.
Both packages implement the LMS method of Cole and Green.  You might  
also
want to consider alternative methods:  an approach based on  
nonparametric
quantile regression is described in:

http://www.ncbi.nlm.nih.gov/sites/entrez? 
cmd=Retrieve&db=PubMed&list_uids=16143984&dopt=AbstractPlus

Some comparison with the LMS method are reported there.

I think you have the reference for the lmreg package
wrong.  It looks like it is Carey VJ. LMSqreg: An R
package for Cole?Green reference centile curves, 2002,
http://www.biostat.harvard.edu/∼carey.

The package seems to be available at
http://www.biostat.harvard.edu/~carey/vcwww_4.html
