给定一组PDF文件,其中一些页面是彩色的,其余的是黑白的,是否有任何程序可以在给定的页面中查找颜色,哪些是黑白？例如,这可以用于打印论文,并且仅花费额外的费用来打印彩色页面.考虑到双面打印的人的奖励积分,并且如果彩色打印机后面是彩色页面,则向彩色打印机发送适当的黑白页面.

我正在尝试创建一个LaTex文档,其中包含"testday"和一个充满"testItemToDo"的诗句,我希望在"testday"之前发生任何分页,但绝不要在"testday"和"testItemToDo"的诗句之间发生.如何修改我的LaTex文件

\documentclass{article}
\begin{document}
\LARGE
{*}{*}to do\\
\begin{verse}
{*}today\nopagebreak
\begin{verse}
testItemToDo\\*testItemToDo\\*testItemToDo\\*testItemToDo\\*testItemToDo\\*testItemToDo\\*testItemToDo\\*testItemToDo

在bash中,我可以根据本网站创建一个带有here-doc的脚本:http: //tldp.org/LDP/abs/html/abs-guide.html#GENERATESCRIPT

(
cat <<'EOF'
#!/bin/bash
#? [ ] / \ = + < > : ; " , * | 
#/ ? < > \ : * | ”
#Filename="z:"${$winFn//\//\\}
echo "This is a generated shell script."
App='eval wine "C:\Program Files\foxit\Foxit Reader.exe" "'$winFn'"'
$App
EOF
) > $OUTFILE

如果我$OUTFILE是一个需要sudo权限的目录,我在哪里放置sudo命令或我还能做些什么来使其工作？

here-document的定义如下:http: //en.wikipedia.org/wiki/Here_document

如何在here-document中键入选项卡？比如这样:

cat > prices.txt << EOF
coffee\t$1.50
tea\t$1.50
burger\t$5.00
EOF

更新:

这个问题涉及的问题:

1. 展开制表符
2. 虽然没有扩大美元符号
3. 将here-doc 嵌入诸如脚本之类的文件中

我有兴趣制作一个带有最小二乘回归线和连接数据点与回归线的线段的图,如图所示,称为垂直偏移:http: //mathworld.wolfram.com/LeastSquaresFitting.html alt text http ://mathworld.wolfram.com/images/eps-gif/LeastSquaresOffsets_1000.gif

我在这里完成了情节和回归线:

## Dataset from http://www.apsnet.org/education/advancedplantpath/topics/RModules/doc1/04_Linear_regression.html

## Disease severity as a function of temperature

# Response variable, disease severity
diseasesev<-c(1.9,3.1,3.3,4.8,5.3,6.1,6.4,7.6,9.8,12.4)

# Predictor variable, (Centigrade)
temperature<-c(2,1,5,5,20,20,23,10,30,25)

## For convenience, the data may be formatted into a dataframe
severity <- as.data.frame(cbind(diseasesev,temperature))

## Fit a linear model for the data and summarize the output from function lm()
severity.lm <- lm(diseasesev~temperature,data=severity)

# Take a look at the data
plot(
 diseasesev~temperature,
        data=severity,
        xlab="Temperature",
        ylab="% Disease Severity",
        pch=16,
        pty="s", …

我希望一次翻译整个段落的大文档,新句子的开头是一致的.以下几乎是我想要做的,虽然它还没有为新句子做对齐.

\documentclass{article}

我是一名研究生,有许多脚本,bibtex的书目数据,乳胶论文草稿,开放式办公室的演示文稿,书写的海报,以及数字和结果数据.我想将所有内容放在版本控制下的一个项目中.然后,当我需要处理诸如参考书目数据之类的部分时,我想检查该子目录,根据需要进行修改并将其合并.我希望能够将一个版本签出到我的家用计算机,并且与我的工作计算机不同,并对每个计算机进行独立更改并最终将它们合并.我还希望能够从这个大项目中查看一段代码并将其与版本导入一个单独的项目中.如果我可以改变,我希望能够将它们合并回原始项目.

根据我的理解,git子树可以做到这一点.

http://github.com/apenwarr/git-subtree

有一个例子与我正在尝试做的事情一致:

http://psionides.jogger.pl/2010/02/04/sharing-code-between-projects-with-git-subtree/

假设我的项目的主干包含目录:(bib bin cfg data fig src todo).

我用的时候

git subtree split -P bib -b export
git checkout export

我得到一个bib目录,加上所有应该被忽略的文件或基于.gitignore的二进制文件,例如src目录以及以tilde或./data目录结尾的所有内容.

dwickrama@DWwork:~/research/trunk$ ls * -r
biblography.bib  JabRef

src:
script1.sh~ README~         script2.sh~
script3.sh~ script4.R~  script5.awk~
script5.py~ 

cfg:
cfgFile1.ini~  cfgFile2.ini~  cfgFile3.ini~

bin:
bigBinaryPackage1   bigBinaryPackage2

dwickrama@DWwork:~/research/trunk$ 

我的.gitignore文件如下:

*.doc diff=word
*.tex diff=tex
*.bib diff=bibtex
*.py diff=python
*.eps binary
*.jpg binary
*.png binary
./bin/* binary
*~

我该如何防止这种情况？

我想从命令行打印一周价值的Google日历事件.我想使用https://www.google.com/calendar/printable而不是某些API是最简单的方法.我需要一些帮助.在下面的命令中,每个参数的含义是什么？

https://www.google.com/calendar/printable?mode=MONTH&wkst=1&hl=en&pgsz=letter&dates=20090801%2F20100531&src=fla-general@forestlake.org&ctz=%3Csomething%3E&src=fla-general@forestlake.org&pfs=NORMAL&po = AUTO&psdec =真重量份=假PJS =假兰特=%3Csomething%3E&PDA =真

我可以在哪里阅读有关此文件的文件？

我需要为下面的图中的置信带之外的数据点着色不同于带内的数据点.我应该在数据集中添加单独的列来记录数据点是否在置信带内吗？你能提供一个例子吗？

示例数据集:

## Dataset from http://www.apsnet.org/education/advancedplantpath/topics/RModules/doc1/04_Linear_regression.html

## Disease severity as a function of temperature

# Response variable, disease severity
diseasesev<-c(1.9,3.1,3.3,4.8,5.3,6.1,6.4,7.6,9.8,12.4)

# Predictor variable, (Centigrade)
temperature<-c(2,1,5,5,20,20,23,10,30,25)

## For convenience, the data may be formatted into a dataframe
severity <- as.data.frame(cbind(diseasesev,temperature))

## Fit a linear model for the data and summarize the output from function lm()
severity.lm <- lm(diseasesev~temperature,data=severity)

# Take a look at the data

  diseasesev~temperature,
  data=severity,
  xlab="Temperature",
  ylab="% Disease Severity",
  pch=16,

我正在使用LaTeX,最近发布了LaTeX Lab,一个用于Google文档的在线LaTeX界面.

在大多数情况下,这个在线LaTeX编译器很棒,我可以得到这样的文档来编译:

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\title{\LaTeX without extra usepackages}
\date{}
\begin{document}
  \maketitle
  I would like to know how to use \LaTeX{} with extra packages.

  % This is a comment; it is not shown in the final output.
  % The following shows a little of the typesetting power of LaTeX
  \begin{align}
    E &= mc^2                              \\
    m &= \frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}}
  \end{align}
\end{document}

但是,使用更多软件包的较大文档无法编译,即使它们在LaTeX的本地安装上也是如此.一个例子如下:
