如何使用ggplot2绘制图形？

Question

我有以下数据。

 $(document).ready(function() {

        alert("hi doc ready"); //added by Shrikant on 14-12-2015 
        $("#issuedDate").datepicker({ changeMonth : true, changeYear : 
        true });
    <div class="user-form.row"> <div class="form-lable"> Issued date 
    :   </div> <div class="form-comp">   <input type="text" size 
    ="5" id="issuedDate" name="issuedDate" required="required" /> 
    </div> </div>

现在，我想使用这些数据绘制下图

您所指的地图不是使用ggplot2，而是使用lattice库。您可以在Quick-R website上找到一些使用lattice的示例。下面我引用本网站提供的代码示例和输出图：

library(lattice)
attach(mtcars)

gear.f<-factor(gear,levels=c(3,4,5),
   labels=c("3gears","4gears","5gears"))
cyl.f <-factor(cyl,levels=c(4,6,8),
   labels=c("4cyl","6cyl","8cyl")) 

bwplot(cyl.f~mpg|gear.f,
   ylab="Cylinders", xlab="Miles per Gallon",
   main="Mileage by Cylinders and Gears",
   layout=(c(1,3)))
