我在网上找到了一些答案,但由于某些原因我的解释不正确,因为我无法让它工作。我的目标是简单地使用xts
绘图功能(以及创建轴,网格线等的方式)来绘制多个绘图:
x <- xts(data.frame(a=1:100, b=100:1),seq(from=as.Date("2010-01-01"), by="days", len=100))
> plot(x, screens=1)
Warning messages:
1: In plot.xts(x, screens = 1) :
only the univariate series will be plotted
2: In plot.window(...) : "screens" is not a graphical parameter
3: In plot.xy(xy, type, ...) : "screens" is not a graphical parameter
4: In axis(1, at = xycoords$x, labels = FALSE, col = "#BBBBBB", ...) :
"screens" is not a graphical parameter
5: In axis(1, at = xycoords$x[ep], labels = names(ep), las = 1, lwd = 1, :
"screens" is not a graphical parameter
6: In axis(2, ...) : "screens" is not a graphical parameter
7: In title(screens = 1) : "screens" is not a graphical parameter
另一次尝试:
> plot(x, plot.type="single")
Warning messages:
1: In plot.xts(x, plot.type = "single") :
only the univariate series will be plotted
2: In plot.window(...) : "plot.type" is not a graphical parameter
3: In plot.xy(xy, type, ...) : "plot.type" is not a graphical parameter
4: In axis(1, at = xycoords$x, labels = FALSE, col = "#BBBBBB", ...) :
"plot.type" is not a graphical parameter
5: In axis(1, at = xycoords$x[ep], labels = names(ep), las = 1, lwd = 1, :
"plot.type" is not a graphical parameter
6: In axis(2, ...) : "plot.type" is not a graphical parameter
7: In title(plot.type = "single") :
"plot.type" is not a graphical parameter
要明确:我可以使用lines
执行此操作,但我想知道是否有办法一次性执行此操作。
答案 0 :(得分:9)
您可以强制zoo
使用plot.zoo
:
plot(as.zoo(x), screens=1)
plot(as.zoo(x), plot.type='single')
或者,您可以安装xtsExtra,其中包含较新的plot.xts
方法
#install.packages("xtsExtra", repos='http://r-forge.r-project.org')
library(xtsExtra)
plot(x, screens=1)
答案 1 :(得分:1)
我可能错了,但我认为plot.xts不再是xtsExtra的一部分而已移至主要的xts。 Source。也许这个笔记将帮助人们在未来试图找出xts中的绘图..
