我是R的新手,使用您的网站非常有帮助。 不幸的是,我一直在努力使用我的代码两天,所以我想要 问几个问题。我一直在努力创造出漂亮的图形 pdf表,但我遇到的所有包都没什么问题 使用。所以我想要完成的是创建一个包含三个的pdf表 图和一个相关表。下面是我创建的一个例子 与我想做的非常相似,但我想做的事情很少 更改。我在quantmod中使用chartSeries来表示图形和表格 我正在使用textplot。
几个问题:
最佳,

#Get the return for last two months and only get close price return.
#because in my data I only have the close price.

一些好问题。
Q1:不。quantmod:::chartSeries.chob
有此代码:
old.adj <- par('adj')
par('adj'=0)
do.call('title',list(x@name, col.main=x@colors$fg.col))
par('adj'=1)
do.call('title',list(paste('[',start(xx),'/',end(xx),']', sep='')
,col.main=x@colors$main.col))
par('adj'=old.adj)
即。起始(xx)/结束(xx)位是硬编码的。
Q2。同样,它似乎是硬编码的(相同功能):
if(x@type=='line') {
lines(x.pos,Closes,col=x@colors$up.col,type=x@line.type)
main.key <- c(list(list(legend=
paste('Last',last(Closes)),
text.col=x@colors$up.col)),main.key)
}
(在我的源代码研究中找不到任何帮助Q3 / Q4 / Q5的内容,抱歉)
