Hi all, I want to calculate interanual (not year to date) variation of a stock, I am able to obtain year to date with annualReturn, but no way to obtain the interanual increase. It says me no numerical output.
Can anyone guide me to obtain it. library(PerformanceAnalytics) library(dplyr) library(tibble) library(lubridate) library(PerformanceAnalytics) library(quantmod) library(ggplot2) library(png) library(RCurl) fecha<-Sys.Date()-365 #with this I obtain one year back beginning precio<-getSymbols("ACX.MC",from='fecha') ret2<- na.omit(CalculateReturns(Cl(ACX.MC))) g<-annualReturn(ACX.MC) #This is year to date d<-CalculateReturns(Cl(ACX.MCC)) aaa<-getQuote('ACX.MC',from='fecha') Lastprice<-aaa[1,2] lo<-c(diff(log(aaa),250)) #With this I try to obtain interanual year variation but error Hope you can help me [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
