Dear friends - I am trying to understand fda and working with the 2009 book from Springer. I run the scripts directly from a new installed fda library and include sessionInfo() below. This is from the script fdarm-ch09.R - I seem to have got not fda_2.2.8 but 2.2.7 - is that the problem? Where do I get .8 as I just reinstalled?

...ive of a spline of order k is a spline of order k-1.) An example is provided in Figure 1.2 of Ramsay, Hooker and Graves (2009) Functional Data Analysis with R and Matlab (Springer). However, you don't have to get to book to see that example. Just work through the script file "fdarm-ch01.R" in system.file('scripts', package='fda') on any computer with the 'fda' package installed. Hope this helps. Spencer On 11/22/2010 7:49 PM, Ravi Varadhan wrote: > Here is a simple approach: > > data<- read.table("test-data.txt&...
