我正在遵循一个教程，并且试图在我的数据上应用某些功能。本教程下载数据的依据；
library(tidyquant)
library(tidyverse)
library(timetk)
symbols <- c("SPY","EFA", "IJS", "EEM","AGG")
prices <-
getSymbols(symbols, src = 'yahoo',
from = "2012-12-31",
to = "2017-12-31",
auto.assign = TRUE, warnings = FALSE) %>%
map(~Ad(get(.))) %>%
reduce(merge) %>%
`colnames<-`(symbols)
以wide格式返回的内容：
> head(prices)
SPY EFA IJS EEM AGG
2012-12-31 125.8673 47.69352 73.92869 39.04684 95.47135
2013-01-02 129.0933 48.43166 75.95714 39.81280 95.35963
2013-01-03 128.8016 47.96195 75.85664 39.53108 95.11894
2013-01-04 129.3673 48.20519 76.45055 39.61031 95.22212
2013-01-07 129.0137 47.99550 76.00284 39.31097 95.17055
2013-01-08 128.6425 47.72708 75.71043 38.95880 95.25651
然后他们应用以下内容；
asset_returns_long <-
prices %>%
to.monthly(indexAt = "lastof", OHLC = FALSE) %>%
tk_tbl(preserve_index = TRUE, rename_index = "date") %>%
gather(asset, returns, -date) %>%
group_by(asset) %>%
mutate(returns = (log(returns) - log(lag(returns)))) %>%
na.omit()
以长格式给出以下输出：
> head(asset_returns_long)
# A tibble: 6 x 3
# Groups: asset [1]
date asset returns
<date> <chr> <dbl>
1 2013-01-31 SPY 0.0499
2 2013-02-28 SPY 0.0127
3 2013-03-31 SPY 0.0373
4 2013-04-30 SPY 0.0190
5 2013-05-31 SPY 0.0233
6 2013-06-30 SPY -0.0134
作者获取了数据，并对to.monthly数据进行了tk_tbl和wide并将其转换为long数据。
我也在尝试应用相同的功能，但是我的数据为long格式。我尝试将其转换为wide格式，但是名称重复。
我的问题是，如何直接在长数据上执行这些功能。我正在尝试的所有操作（转换为wide，grouping_by等均返回错误的结果）。
我正在使用的数据如下：
ID date prc
2015-06-02 "88250810" "2015-06-02" "55.250"
2015-06-02 "40414L10" "2015-06-02" "38.910"
2015-06-03 "88250810" "2015-06-03" "54.885"
2015-06-03 "40414L10" "2015-06-03" "38.240"
2015-06-04 "88250810" "2015-06-04" "53.980"
2015-06-04 "40414L10" "2015-06-04" "38.290"
该功能来自beow链接，可将每日价格转换为月度日志回报。

设置为ts。
d <-as.xts（d，order.by = d $ date）

答案 0 :(得分：1)
如果问题是如何从data创建一个宽幅时间序列，则这会从动物园对象z创建一个宽幅时间序列。您可以直接使用它，或者如果需要data.frame，请使用fortify.zoo(z)，或者如果您需要xts对象，请使用as.xts(z)。
library(zoo)
z <- read.zoo(data, index = "date", split = "ID")
