I am estimating Value at Risk using PerfomanceAnalytics package. The?variables are stored in a data frame. I formated the data variables using zoo() and as.xtx() but it is not working. The working example is below. ##########################################################? reguire(zoo) require(PerformanceAnalytics) reguire(xts) ? year<- c(1991-12-30, 1992-12-30, 1993-12-30, 1994-12-30) R1 <- c(12, 9, 8, 13) R2 <- c(5,2,9, 13) d? <- data.frame(cbind(year, R1,R2)) ? d<- zoo(d,year)? VaR(d) #Error in checkData(R, method = "xts", ...) ? #When I use d &l...

...th the look and functionality. Except in one, very important, way. I can??t figure out how to get the ~ sign from the keyboard to the console. Copying it from old code works fine. Using the traditional GUI works as usual. I have a Swedish keyboard layout, where ~ shares key with ?? and ^, all reguiring a space after the hit to produce the sign on the screen.

A friend has an old Pentium-133 laptop with 32MB of memory and a 1.3 GB hard disk that he wants to use as a web server for a very small community. Will CentOS (or any other RHEL derived distribution for that matter) install and run with acceptable performance on such a system, or will a specialized distribution like Damn Small Linux be a better choice? In this case, disk space is not a big
