> Dear Sirs,
> I am trying to perform a garch analysis to some data time series.Therefore, I've downloaded the package "tseries", as the garch analysis is not available in the main R  program.When I try to load the "tseries package" from the R-Console screen, the following message appears:
> local({pkg <- select.list(sort(.packages(all.available = TRUE)))
> + if(nchar(pkg)) library(pkg, character.only=TRUE)})
> Loading required package: quadprog 
> Error: package 'quadprog' could not be loaded
> In addition: Warning message: 
> There is no package called 'quadprog' in: library(pkg, character.only = TRUE, logical = TRUE, lib.loc = lib.loc) 

Do you have quadprog installed?

> It seems that the program detects a failure in a package called "quadprog", which I can't find (while I am trying to select the "tseries" package). As a consequence I cannot use the "garch" command.Could you lend me a helping hand on this issue?.
