ggplot2是R中新颖的数据可视化包,这得益于Leland Wilkinson在他的著作《The Grammar of Graphics》中提出了一套图形语法,把图形元素抽象成可以自由组合的成分,Hadley Wickham把这套想法在R中实现。 1. How to use qplot 函数qplot()是ggplot2中十分常用的函数,使用它可以绘制丰富多彩的图形,并且通常只需要一行代码可...
binwidth argument in your qplot() function: qplot(chol$AGE, geom="histogram", binwidth = 0.5) Names/colors As with the hist() function, you can use the argument main to change the title of the histogram: qplot(chol$AGE, geom="histogram", binwidth = 0.5, main = "Histogram for...
ggplot(data=home_data,aes(x=price))+geom_histogram(binwidth=50000) Finally, you can align the boundaries using the center or boundary attributes. If you want the boundaries of bins to fall on specific multiples, you can use these attributes (only one can be used at a time). To ensure ...

1、What is ggplot2 ggplot2基本要素 数据(Data)和映射(Mapping) 几何对象(Geometric) 标尺(Scale) 统计变换(Statistics) 坐标系统(Coordinante) 图层(Layer) 分面(Facet) 这里将从这些基本要素对ggplot2进行介绍。 2、数据(Data)和映射(Mapping) 以R自带的钻石的数据为例,由于样本量十分巨大,我们随机取一个子集...
Use coord_cartesian() instead to alter the axis bounds without losing data observations. The coord_cartesian() function provides the x- and y-axis bounds without removing observations. How to Set Axis Limits in ggplot2 Using the scatterplot below, which was created using the built-in R datase...

Let’s assume that we want to draw our data in a ggplot2barplot. Then, we might try to use the following R code: ggplot(data, aes(Group, mean))+# ggplot function leads to errorgeom_bar(stat="identity")# Don't know how to automatically pick scale for object of type standardGeneric....

Error in ggplot(., aes(x = Species, y = Sepal.Length, fill = Species)) : could not find function "ggplot" This ggplot2 error is telling us that it could not find the function ggplot() to make the plot that we desired. One of the reasons is that we have installed ggplot2, but ...
