I'm developing VAR analysis based on suggestions made by Horváth in its

uroot Package and R 2.12.1
Hello friends.
I'm wondering what happened to package uroot. I worked quite well with
older versions of R, however with 2.12.1 version it simply doesn't work.
The worst thing is that I look for it in the contributed packages and it

I am a biginner of R.
I have difficulty with reading the code of a method.
I am using the vars package to estimate a VAR model and I want to view the code of "predict" method for objects with class attribute "varest".

Export successively displayed graphics
Hello,
I am running R version 2.4.1 on Debian.
I am using some R functions which produce several graphics displayed
successively with an interactive prompt between each graph. For example,
the plot.varest (vars) function produces such output (one graph per time
series on which the VAR model is fitted). Plots on GARCH models also
produce such outputs.
Moreover, the frontend I am using for R
