R和XML：‘下标越界’错误
R和XML：‘下标越界’错误
提问于 2020-12-23 21:01:54
我在这里做错了什么？我的R代码：
u <- "http://www.cbr.ru/scripts/xml_depo.asp?date_req1=01/07/2001&date_req2=22/12/2020"
f <- xml2::read_xml(u)
doc <- xml2::as_list(f)
d <- lapply(doc$Deposit,
function(x) data.frame(Overnight = x$Overnight[[1]],
Tom_next = x$`Tom-next`[[1]],
Spot_next = x$`Spot-next`[[1]],
Spot_week = x$`Spot-week`[[1]],
P2weeks = x$P2weeks[[1]],
Spot_2week = x$`Spot-2week`[[1]],
P1month = x$P1month[[1]],
P3month = x$P3month[[1]],
Date = attr(x, "Date")))
d <- dplyr::bind_rows(d)它在d <- lapply(doc$Deposit,...的行处中断，说Error in x$Overnight[[1]] : subscript out of bounds。

我认为你应该把d <- lapply(doc$Deposit,...改成d <- lapply(doc$Deposit$Record,...
请尝试
d <- lapply(doc$Deposit$Record,
function(x) data.frame(Overnight = x$Overnight[[1]],
Tom_next = x$`Tom-next`[[1]],
Spot_next = x$`Spot-next`[[1]],
Spot_week = x$`Spot-week`[[1]],
P2weeks = x$P2weeks[[1]],
Spot_2week = x$`Spot-2week`[[1]],
P1month = x$P1month[[1]],
P3month = x$P3month[[1]],
Date = attr(x, "Date")))
d <- dplyr::bind_rows(d)编辑：
很抱歉，在没有进一步检查的情况下，我仓促地提出了这一点。我建议这样做：
d <- lapply(doc$Deposit$Record, cbind)
d <- as.data.frame(t(unlist(d)))
d
# Overnight Tom-next Spot-next P1week Spot-week P2weeks Spot-2weeks P1month P3month
