描述----------Description----------
plot.snp.dprime takes a snp.dprime object and draw an eps file to visualize the pairwise D', $r^2$ and LOD.
plot.snp.dprimesnp.dprime对象，并绘制一个EPS文件，以可视化成对D“，$ R ^ 2 $和LOD。
用法----------Usage----------
## S3 method for class 'snp.dprime'
plot(x, filename, scheme = "standard", do.notes = FALSE,
metric=NULL, ...)
参数----------Arguments----------
参数：x
An object of class snp.dprime
一个对象的类snp.dprime
参数：filename
The output file name, preferably ending with ".eps" (not enforced)
输出文件的名称，最好是用“易办事”结束（不执行）
参数：scheme
The colour scheme used. Valid values are "standard" for the Haploview default, and "rsq" for grayscale $r^2$. More may come later
使用的配色方案。有效值是“标准”为Haploview违约，“RSQ”灰度$ R ^ 2美元。更可能晚一点
参数：do.notes
Boolean for whether to generate pdf annotation-related code
布尔为是否生成PDF的注释相关的代码
参数：metric
An integer vector, detailing the chromosome position of the SNP, to drawa scaled metric of the location of the SNP. If NULL, no metric would be drawn
整数向量，详细介绍了染色体SNP的位置，drawa规模度量的SNP的位置。如果为NULL，没有标准将制定
参数：...
place holder
占位
Details
详情----------Details----------
Annotation is a little used pdf features where certain part of a pdf file are hot spots where one can get pop-up balloons containing extra information, which doesn't appear in print. This is written to imitate the extra information one can get from right-clicking in Haploview's GUI.
注解是一点点的一个pdf文件的某一部分是热点，其中一个可以包含额外的信息，它不会出现在打印的弹出气球的PDF功能。这是书面的，额外的信息可以从Haploview的图形用户界面中右键单击模仿。
值----------Value----------
return nothing. Write a file as a result. And if do.notes is specified, Will also suggest user to execute ps2pdf -dEPSCrop <filename> to get a suitable pdf.
返回任何结果。结果写入一个文件。和do.notes如果是指定的，也将建议用户执行ps2pdf -dEPSCrop <filename>得到一个合适的PDF。
注意----------Note----------
Unfortunately, there are two problems with annotations: only Acrobat Reader (out of all the pdf viewers, e.g. xpdf, kpdf, evince, various ghostscript based viewers) implements the feature, and a few thousand annotations can really make Acrobat Reader crawl.
不幸的是，这里有两个问题与注释：只有使用Acrobat Reader（出所有的PDF浏览器，如xpdf的KPDF，表示出各种基于观众的ghostscript）实现该功能，几千元的注解真的可以使用Acrobat Reader抓取。
Also, Acrobat Reader has an implementation limit of 200 inches of the widest dimension of a document. This translates to 1200 snps in the current implementation of the drawing code, hence a warning is emitted that pdf written this way is not viewable by Acrobat Reader.(but viewable by xpdf, etc). A work around is possible based on LaTeX pdfpage, or eps can be included with scaling in another document, to stay inside 200 inches.
另外，Acrobat Reader有一个最广泛的文档尺寸200英寸的实施期限。这意味着到1200个SNPs在当前的绘图代码的执行，因此发出警告，PDF这样写是不可见的Acrobat Reader。（但xpdf的等可视）。围绕一个工作可能是基于对乳胶pdfpage，或EPS可包含在另一个文档的缩放，200英寸留在里面。
In the future, one might want to put some additional scaling code to fit the whole drawing within an A4, for example.
在未来，人们可能会希望把一些额外的缩放代码，例如，适合整个绘图在一张A4。
There is a Google Summer of code http://code.google.com/soc/ 2006 project to improve kpdf's annotation support. http://wiki.kde.org/tiki-index.php?page=KDE%20Google%20SoC%202006%20ideas#id60851 I am involved.
有一个代码http://code.google.com/soc/ 2006年项目，以改善KPDF的注解支持的Google的夏季。 http://wiki.kde.org/tiki-index.php?page=KDE％20Google％20SoC％202006的％20ideas＃id60851我参与。
