我正在尝试合并2个xts对象，其中第二个对象需要在第一个对象中填充新列-如果缺少值，请填充0
基本上，我有这两个xts对象
str(x1)
An ‘xts’ object on 1999-01-01/2019-06-14 containing:
Data: num [1:5336, 1:14] 0.611 0.614 0.62 0.623 0.629 ...
- attr(*, "dimnames")=List of 2
..$ : NULL
..$ : chr [1:14] "Open" "High" "Low" "Close" ...
Indexed by objects of class: [Date] TZ: UTC
xts Attributes:
NULL
> str(x2)
An ‘xts’ object on 1999-03-25/2019-04-25 containing:
Data: chr [1:202, 1] "enter_long" "exit_long" "enter_long" "exit_long" "enter_long" "exit_long" "enter_long" "exit_long" ...
- attr(*, "dimnames")=List of 2
..$ : NULL
..$ : chr "Rule"
Indexed by objects of class: [Date] TZ: UTC
xts Attributes:
NULL
我的x1对象看起来像这样
head(x1)
Open High Low Close N MA1 MA2 MA3 MA3_curve buy_signal exit_buysignal sell_signal exit_sellsignal pos
1999-01-01 0.6114 0.6138 0.6098 0.6103 NA 0.00000 0 0 NA 0 0 0 0 0
1999-01-04 0.6137 0.6201 0.6112 0.6182 NA 0.00000 0 0 NA 0 0 0 0 0
1999-01-05 0.6198 0.6255 0.6193 0.6224 NA 0.00000 0 0 NA 0 0 0 0 0
1999-01-06 0.6227 0.6305 0.6192 0.6283 NA 0.00000 0 0 NA 0 0 0 0 0
1999-01-07 0.6288 0.6354 0.6275 0.6348 NA 0.62280 0 0 NA 0 0 0 0 0
1999-01-08 0.6347 0.6384 0.6313 0.6339 NA 0.62752 0 0 NA 0 0 0 0 0
第二个x2对象看起来像这样
Rule
1999-03-25 "enter_long"
1999-03-30 "exit_long"
1999-04-14 "enter_long"
1999-05-31 "exit_long"
1999-06-10 "enter_long"
1999-06-18 "exit_long"
当我使用
i <- cbind.xts(x1,x2, fill = "0")
它用0正确填充丢失的值，但用 NA 填充现有值 这是错误消息
Warning message:
In merge.xts(..., all = all, fill = fill, suffixes = suffixes) :
NAs introduced by coercion
我已经尝试了所有发现的东西 -merge.xts / cbind.xts -从dplyr查找 -....
感谢您的帮助
