Hi group, I am trying to convert the organization of a data frame so I can do some correlations between stocks, I have something like this: stock.returns <- data.frame(rbind(c("MSFT","20110301",0.05),c("MSFT","20110302",0.01),c("GOOG","20110301",-0.01),c("GOOG","20110302",0.04))) colnames(stock.returns) <- c("Ticker","Date","Return") stock.returns Ticker Date Return 1 MSFT 20110301 0.05 2 MSFT 20110302 0.01 3 GOOG 20110301 -0.01 4 GOOG 201103...

Hey guys, i want to calculate the continuasly compounded returns for stock prices. Formula for CCR: R_t = ln(P_t/P_{t-1})*100 With R: First i have to modify the vectors, so that they have the same length and we start at the second observation. log(GOOG1[-1]/GOOG1[1:length(GOOG1)-1])*100 That does work with normal vectors. My Questions: 1) I want to use this for stock prices. so i use: library(quantmod) getSymbols("GOOG",from="2011-11-01") GOOG1<-GOOG[,1] If i use my formula i get only the value "1" for e...

Ultimately I want to be able to do returns("GOOG"), and have the output in this format: funds 12mo GOOG 14% I've tried using as.character(), quote(), dQuote(), sQuote(), gsub(), cat(), and a bunch of combinations of them.

Hi, As I mentioned some time ago on the mailing list, I'm working on the implementation of the Sarkar's Extended Linear Scan algorithm for LLVM. For testing and debugging of this algorithm, I need some good test-cases that check different functionalities of the register allocator, e.g.: - test-cases involving a lot of spilling - test-cases using pre-colored registers, e.g. like the EAX

Please, Where can I find a list of repositories all over internet.. I want to keep my CentOS servers up 2 date with mailscanner, clamAV, syslog-ng, and others... I know dag has a very goog one but there are some paktes I can not find in dag repository like mailscanner, syslog-ng, among others... Sorry if it's offtopic but I need it! Thanks in advance Regards, israel
