expon

a vector of values at which the basis functions are to be evaluated.

a vector of rate or time constants defining the exponential
functions.  That is, if $a$ is the value of an
element of this vector, then the corresponding basis function
is $exp(at)$. The number of basis functions is equal
to the length of <code>ratevec</code>

ratevec

a nonnegative integer specifying an order of derivative to
be computed.  The default is 0, or the basis function value.

nderiv

Evaluates a set of exponential basis functions, or a derivative of these
functions, at a set of arguments.

These functions were developed to support functional data
        analysis as described in Ramsay, J. O. and Silverman, B. W.
        (2005) Functional Data Analysis. New York: Springer.  They were
        ported from earlier versions in Matlab and S-PLUS.  An
        introduction appears in Ramsay, J. O., Hooker, Giles, and
        Graves, Spencer (2009) Functional Data Analysis with R and
        Matlab (Springer). The package includes data sets and script
        files working many examples including all but one of the 76
        figures in this latter book.  Matlab versions of the code and
        sample analyses are no longer distributed through CRAN, as they
        were when the book was published.  For those, ftp from
        http://www.psych.mcgill.ca/misc/fda/downloads/FDAfuns/
        There you find a set of .zip files containing the functions and
        sample analyses, as well as two .txt files giving instructions for
        installation and some additional information.
