My aim is to get 1 plot in which there is multiple times series with an auto legend to identify the series. In my CSV file I have 5 columns (agri, food, fuel, manu, ores) starting from January,1996.
我的目标是得到一个情节，其中有多个时代系列与一个汽车图例识别系列。在我的CSV文件中，从1996年1月起，我有5个栏目(agri, food, fuel, manu, ores)。
library(xts)
library(xtsExtra)
RuChAgri <- read.csv("https://dl.dropbox.com/u/6421260/Forum/RuChAgri.csv", sep=";")
#transform csv data according to R ts
RuChAgri <- ts(RuChAgri, start = c(1996, 1), frequency = 1)
#try to get 1 plot with multiple ts with an auto legend
plot.xts(RuChAgri, screens = factor(1, 1), auto.legend = TRUE)
When I run last line I get the error:
当我运行最后一行时，我得到了错误:
Error in try.xts(x) :
Error in xts(x.mat, order.by = order.by, frequency = frequency(x),
.CLASS = "ts", : NROW(x) must match length(order.by)
Does someone know what is wrong with my code?
有人知道我的代码有什么问题吗?

Your ts object isn't well-constructed. The series is monthly, so the frequency should be 12, not 1.
你的ts对象构造得不好。这个级数是每月的，所以频率应该是12，而不是1。
RuChAgri <- ts(RuChAgri, start=c(1996, 1), frequency=12)
Then you should convert it to an xts object and then call plot.xts by calling plot. You really shouldn't call plot.xts directly, even though it tries to convert the object you give it to an xts object...
然后将它转换为xts对象，然后调用plot。xt通过调用阴谋。你真的不应该叫阴谋。直接使用xts，即使它试图将您给它的对象转换为xts对象……
x <- as.xts(RuChAgri)
plot(x, screens=factor(1, 1), auto.legend=TRUE)
