描述----------Description----------
correlationPlot The correlationPlot can be used to vizualize e.g. the correlation between the mean binding intensity of specific regions around annotated features and gene expression. The regions around the annotated features, that should be analyzed are defined in a data frame. Each row represents one region. In the upper panel of the plot, the correlation is plotted in a barplot. In the lower panel, the annotated feature and the regions defined in the data frame are shown.
correlationPlot的correlationPlot可以用来vizualize如注解功能和基因表达周围的特定区域的平均结合强度之间的关系。周围的注释功能的区域，应分析是指在一个数据框。每一行代表一个区域。在上游面板的图，绘制相关在barplot。在下部面板上，注明的功能和数据框中定义的区域。
用法----------Usage----------
correlationPlot(regions, labels=c("start", "stop"), ...)
参数----------Arguments----------
参数： regions
a data frame, containing four columns. Every row defines one region to be analyzed and is plotted in the lower panel. pos=start, upstream=500 and downstream=500 mean characterize the region 500 bp upstream and downstream around the start of the feature. The pos columns is a character with values out of c("start", "region", "end"). upstream and downstream ar integers, indicating how many bases upstream and downstream from the specified position in the feature are included. level is an integer, that says at which level the rectangle in the lower device should be plotted. The numeration goes from the bottom to the ceiling. cor is the correlation of the region, which is plotted in the upper panel.
一个数据框，其中包含四列。每一行定义一个区域进行分析，并在下部面板上绘制。 POS =开始，上游= 500和下游= 500平均表征功能开始周围区域的500 bp的上游和下游。在POS列是一个字符c值（“开始”，“区域”，“结束”）。上游和下游的的AR整数，表示多少碱基的上游和下游，在指定位置的功能包括。 level是一个整数，说在哪个级别的矩形应绘制在较低的设备。在记数从底部到天花板。心病是该区域的相关性，这是在上游面板绘制。
参数： labels
a character vector which holds the names of the borders of the annotated region. (e.g. c("TSS", "TTS") for transcripts)
持有的注解区域的边界的名称字符向量。 （例如：C（“TSS的”，“语音合成”）的成绩单）
参数：...
parameters, that are passed to barplot (for plotting the upper panel)
参数，这是传递到barplot的（图上游面板）

## Constructing an example data frame[＃构建一个例子数据框]
pos <- c("start", "start", "start", "region", "region","region","region", "stop","stop","stop")
upstream <- c(500, 0, 250, 0, 0, 500, 500, 500, 0, 250)
downstream <- c(0, 500, 250, 0, 500, 0, 500, 0, 500, 250)
level <- c(1, 1, 2, 3, 4, 5, 6, 1, 1, 2)
cor <- seq(-1,1, length=10)
info <- data.frame(pos=pos, upstream=upstream, downstream=downstream, level=level, cor=cor, stringsAsFactors=FALSE)
rownames(info) <- letters[1:10]
