以下是XML代码:

使用以下R代码:
library(ggplot2)
library (XML)
test.df <- xmlToDataFrame(file.choose())
test.df
sapply(test.df, class)
test.df$timeStamp <- strptime(as.character(test.df$timeStamp), "%H:%M:%OS")
test.df$Price <- as.numeric(as.character(test.df$Price))
sapply(test.df, class)
options("digits.secs"=3)
summary (test.df)
with(test.df, plot(timeStamp, Price))
sd (test.df$Price)
mean(test.df$timeStamp)
test.df$timeStamp <- test.df[1,"timeStamp"] + cumsum(runif(7)*60)
summary(test.df)
qplot(timeStamp,Price,data=test.df,geom=c("point","line"))
Price <- summary(test.df$Price)
print (Price)
我想创建一个交互式图表,允许用户点击某个点并获得该点的值信息(例如,如果该值有异常跳动)。我希望能够将此交互式图表放在网页上。有人建议使用GGOBI来实现这一点,而其他人则说可以留在R中并使用rggobi库。由于我对此没有任何经验,所以我想寻求一些指针,直接或指向特定资源(在网络上搜索多年仍然找不到任何东西)。
在图表下面,我想打印出价格的摘要。目前我在Windows上运行代码批处理文件,并返回pdf文件中的图表,但没有摘要打印。是否有一种方法可以设置代码/BATCH文件,使其可以生成交互式图表和摘要?
