[R] creating time series from existing data

[Philippe Grosjean]

Hello,
You will find many tools for this purpose in the pastecs package. There are
4 regulation methods provided for transforming irregularly spaced
observations into regular time series: constant regconst(), linear reglin(),
spline regspline() (these three functions are just nice wrappers around the
approx() and spline() functions provided in the base R package), and also
the very powerful area method regarea(). In addition to the online help in
English, you will find additional explanations, examples and theoretical
explanations in the user manual (currently only in French) that you can
download from  http://www.sciviews.org/pastecs. Hope this will help.
Best,

Philippe Grosjean

Is it possible to create a time series from existing data frame? One
column of that frame contains dates (like "01/01/01") and the second one
the values. The period is non-regular (it is not strictly daily nor
working-days-daily).
Thank you.
