我试图将merge / join两个对象放在一起，一个是xts对象，另一个是列表。我想将数据保留为xts对象（因此将第二个数据与我在下面发布的第一个数据合并）。基本上，Data 2包含Data 1的预测概率。
我尝试将数据2创建为data.frame并取消列出，然后将其by = "index(data)"合并，但是失败了。
数据的维度如下：
dim(dat)
212 4
prob_predictions <- as.data.frame(unlist(probs))
dim(prob_predictions)
191 1
我也在尝试子集（index（df1）％in％index（df2））
数据1：
dat <- structure(c(0, 1, 0, 0, 1, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 0, 1,

以下作品。您可以不列出或创建概率的命名向量。然后创建一个xts对象，但是需要在问题名称（或data.frame中的行名）上使用as.Date，否则尝试将字符值与dat xts的日期值合并。 / p>
library(xts)
# creates a named vector
vals_probs <- sapply(probs, `[`)
# also works
# vals <- data.frame(unlist(probs))
# need to set the names as dates otherwise they are characters
probs_xts <- xts(vals, as.Date(names(vals)))
tail(merge(dat, probs_xts))
y x1 x2 x3 probs_xts
