使用knitr从R中编写html

也许我错过了显而易见的事情,但我一直在努力寻找以下示例：我想使用knitr包将我在R中的分析报告写入html文件.我已经找到了stitch()函数,但是更好地控制哪些结果&情节写入html,哪些不是.原则上我希望能够编写以下代码：

# some dummy code
library(ggplot)
data <- read.table('/Users/mydata',header=TRUE)
model <- lm(Y~X*Y,data)

# write this result to html:
summary(model)

解决方法

我想我不明白你到底缺少什么,但这里有一个我做过的最小例子.要运行它

library(knitr)
knit("r-report.html")

而这个例子.

<HTML>
<HEAD>
  <TITLE>Analyzing Diamonds!</TITLE>
</HEAD>

<BODY>
<H1>Diamonds are everywhere!</H1>

<!--begin.rcode echo=FALSE

## Load libraries,but do not show this
library(ggplot2)
library(plyr)
testData <- rnorm(1)
end.rcode-->

This is an analysis of diamonds,load the data.<p>
<!--begin.rcode echo=TRUE,fig.keep="all"
# Load the data
data(diamonds)
# Preview
head(diamonds)
end.rcode-->

Generate a figure,don't show code <p>
<!--begin.rcode echo=FALSE,fig.align="center",dev="png"
# This code is not shown,but figure will output
qplot(diamonds$color,fill=diamonds$color) + 
  opts(title="A plot title")
end.rcode-->

Show some code,don't output the figure<p>
<!--begin.rcode echo=TRUE,fig.keep="none"
# Show the code for this one,but don't write out the figure
ggplot(diamonds,aes(carat,price,colour=cut)) + 
  geom_point(aes(alpha=0.9))
end.rcode-->


And the value testData: <!--rinline testData --> inside a text block.

</BODY>
</HTML>
