ES function gives the below error. > ES(sim, p=.95, method=c("modified"),portfolio_method=c("component"), > weights=w1) /Error in checkData(R, method = "xts", ...) : The data cannot be converted into a time series. If you are trying to pass in names from a data object with one column, you should use the form 'data[rows, columns, drop = FALSE]'.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I need to count the covariance of two time series. Both of them contain the dates' vector and vector of values. But the dates are not the same. It means some dates of first ts are not in the second respectively. And I need the covariance of same dates, of course. Could anyone help me, please? Thank you. lukas - -- Lukas Kubin lukas.kubin at

Dear helpers, I have multiple vignette files for a package, and I would like to have the "right" order of these files when displayed online. For instance, see below: https://cran.r-project.org/web/packages/bst/index.html The order of vignette links on CRAN is different from what I hoped for: > vignette(package="bst") Vignettes in package 'bst': pros

Hello Forum, I have a problem with the strptime function. With the ''data1'' dataset below it works fine, but with the ''data2'' dataset something goes wrong (see final line below). Both data1 and data2 are in exactly the same original format, the only difference is that they span different dates. Please help, since it is driving me nuts! Many thanks. Best

I think the online order of vignette files are not based on vignette title or filename alphabetically. I am just curious: by what order these vignette files were displayed online so I can make changes accordingly?

These files are not installed when building/installing R. It would appear that they are not included in: https://svn.r-project.org/R/branches/R-2-11-branch/share/Makefile.in The
