提取 xts 对象的数值 [英] Extracting the numerical values of a xts object

问题描述

我想提取一个 xts 对象的数值.我们来看一个例子

I want to extract the numerical values of a xts object. Let's look at an example

data <- new.env()
starting.date <- as.Date("2006-01-01")
nlookback <- 20
getSymbols("UBS", env = data, src = "yahoo", from = starting.date)
Reg.curve <- rollapply(Cl(data$UBS), nlookback, mean, align="right")

Reg.cuve 仍然是一个 xts 对象，但实际上我只是对运行方式感兴趣.如何修改 Reg.curve 以获得数值向量?

The Reg.cuve is still a xts object but actually I'm just interested in the running means. How can I modify Reg.curve to get a numerical vector?

推荐答案

使用coredata:

reg.curve.num <- coredata(Reg.curve)
# or, if you want a vector:
reg.curve.num <- drop(coredata(Reg.curve))
