[R] fit a time varying coefficient log linear model in r

2013-09-24 Thread shanxiao
Hello, all, 

 

Does anyone know any package in r to fit a log linear model with time
varying coefficients in R? I have googled but with no results. Your help
will be appreciated. J

[R] constructing a daily time series

2013-07-22 Thread shanxiao
Dear all, 

 

I have a vector of observations through day, and based on it, I try to
construct a daily time series with the R function ts(), but it seems that it
only enables to construct a weekly, monthly, quarterly and yearly time
series, does anyone know whether there is an option to build a daily time
series? Thanks.

[R] plot discrete time series against time

2013-07-21 Thread shanxiao
Dear all, 

 

I try to plot some discrete time series data through time, of course I can
achieve it by using the combination of some basic R functions, but it is not
that convenient, does anyone know any R-inbuilt function to do it? Best.
