当我尝试“编织HTML”或使用LyX生成pdf时，我遇到了环境问题。 当我直接运行R代码（或者用Rstudio编译HTML笔记本）时，没关系。 我已经用[email protected]（开发版）完成了测试。我没有与[email protected]当在R文件中找到文件时，eval（expr，envir，enclos）中的错误
问题上（test.Rhtml> test.R> init.R> kCommon.R）后，这里给出的样本，返回的错误是：
Period: From
Error in eval(expr, envir, enclos) : objet 'kStartDate' introuvable
to
Error in eval(expr, envir, enclos) : objet 'kEndDate' introuvable
test.R
## @knitr INIT
source("./init.R")
print(kStartDate)
print(kEndDate)
test.R源init.R
if (!require(xtable)){
install.packages("xtable")
library(xtable)
}
source("./kCommon.R")
init.R源kCommon.R
# Period
kStartDate <- as.Date("2013-01-01", format="%Y-%m-%d")
kEndDate <- as.Date("2013-06-30", format="%Y-%m-%d")
test.Rhtml
<html>
<head>
<title>TEST</title>

output <- "html"
read_chunk('test.R')
opts_chunk$set(fig.width=7, fig.height=4.5, fig.align='center', tidy=FALSE, comment=NA)
end.rcode-->
<!--begin.rcode INIT, echo=FALSE, message=FALSE, warning=FALSE

我不能用knitr v1.3.7重现问题;你可以添加'库（knitr）; sessionInfo（）'的输出到你的文章？ –
我在帖子中添加了会话信息。 – abret
你可以在'INIT'中删除块选项'echo = FALSE，message = FALSE，warning = FALSE'，再次编译test.Rhtml并粘贴那个块的输出？ –
