使用Rbbg的R烛光图

我正在尝试使用Rbbg包在R中绘制蜡烛图，如下所示

library(Rbbg)
library(quantmod)
currency <- c("NZD Curncy") 
fld <- c("PX_OPEN", "PX_HIGH", "PX_LOW","PX_LAST") 
crcy<-as.xts(bdh(conn,currency, fld,Sys.Date()-365))
candleChart(crcy)

这是我们的调查结果

head(bdh(conn, currency, fld, Sys.Date()-365)) 

ticker       date PX_OPEN PX_HIGH PX_LOW PX_LAST
1 NZD Curncy 2013-10-28  0.8283  0.8333 0.8272  0.8302
2 NZD Curncy 2013-10-29  0.8302  0.8305 0.8234  0.8258
3 NZD Curncy 2013-10-30  0.8258  0.8287 0.8193  0.8266
4 NZD Curncy 2013-10-31  0.8266  0.8311 0.8231  0.8263
5 NZD Curncy 2013-11-01  0.8263  0.8286 0.8210  0.8268
6 NZD Curncy 2013-11-02      NA      NA     NA      NA

请帮助我更改要导入的数据类型

谢谢你帮我解决上述问题

我遇到了另一个问题

这只让我看到了折线图而不是蜡烛图。OHCL数据中是否存在任何问题？

我们的包装RBBG扩展使这项工作变得简单，只是您仍然需要手动将列名更改为quantmod包所接受的正确列名

下面是没有适当标题的烛光图等，工作由你决定

你从哪里得到坎德哈特的？这不是基本数据，你应该显示dputheadbdhconn、currency、fld、Sys.Date-365的输出，因为这里的大多数人都没有彭博社。您的问题是，第一列包含字符日期，这导致as.xts将整个矩阵强制为字符。尝试使用.xtsx[，-1]，其中x是bdh调用的输出。谢谢。我想坎德克哈特是从quantmod软件包来的。当我申请as.xtsx[，-1].as.quantmod.OHLC帮助我时，它非常有效。谢谢
