Re: [R] Time series: xts/zoo object at annual (yearly) frequency
Maybe one of these are close enough: xts(c(2, 4, 5), yearqtr(1991:1993)) as.xts(ts(c(2, 4, 5), 1991)) of if you want only a plain year as the index then then use zoo, zooreg or ts class: library(zoo) zoo(c(2, 4, 5), 1991:1993) zooreg(c(2, 4, 5), 1991) ts(c(2, 4, 5), 1991) On Fri, Oct 6, 2017 at 2:56 AM, Johnwrote: > Hi, > >I'd like to make a time series at an annual frequency. > >> a<-xts(x=c(2,4,5), order.by=c("1991","1992","1993")) > Error in xts(x = c(2, 4, 5), order.by = c("1991", "1992", "1993")) : > order.by requires an appropriate time-based object >> a<-xts(x=c(2,4,5), order.by=1991:1993) > Error in xts(x = c(2, 4, 5), order.by = 1991:1993) : > order.by requires an appropriate time-based object > > How should I do it?

Re: [R] Time series: xts/zoo object at annual (yearly) frequency
Hi John, Here's one way to do it: vec <- c(2,4,5) yrs <- seq(from=as.Date("1991-01-01"),by="1 year",length=length(vec)) a <- xts(x=vec, order.by=yrs) HTH, Eric On Fri, Oct 6, 2017 at 9:56 AM, Johnwrote: > Hi, > >I'd like to make a time series at an annual frequency. > > > a<-xts(x=c(2,4,5), order.by=c("1991","1992","1993")) > Error in xts(x = c(2, 4, 5), order.by = c("1991", "1992", "1993")) : > order.by requires an appropriate time-based object > > a<-xts(x=c(2,4,5), order.by=1991:1993) > Error in xts(x = c(2, 4, 5), order.by = 1991:1993) : > order.by requires an appropriate time-based object > > How should I do it?

[R] Time series: xts/zoo object at annual (yearly) frequency
Hi, I'd like to make a time series at an annual frequency. > a<-xts(x=c(2,4,5), order.by=c("1991","1992","1993")) Error in xts(x = c(2, 4, 5), order.by = c("1991", "1992", "1993")) : order.by requires an appropriate time-based object > a<-xts(x=c(2,4,5), order.by=1991:1993) Error in xts(x = c(2, 4, 5), order.by = 1991:1993) : order.by requires an appropriate time-based object How should I do it? I know that to do for quarterly or monthly time series, we use as.yearqtr or as.yearmon. What about annual?
