在单个显示器中绘制几个jpeg图像 [英] Plotting several jpeg images in a single display

问题描述

我需要在单个组合显示（或画布？）中绘制和显示几个jpeg图像。例如，假设我有不同大小的图像{a，b，c，d} .jpg，我想在2x2网格中将它们绘制在一个页面上。能够为每个子图设置一个标题也是很好的。

I need to plot and display several jpeg images in a single combined display (or canvas?). For example, suppose I have images {a,b,c,d}.jpg, each of different size, and I would like to plot them on one page in a 2x2 grid. It would be also nice to be able to set a title for each subplot.

我一直在寻找解决方案，但无法找到怎么做它，所以任何想法都会有所帮助。我最好使用基于EBImage包的解决方案。

I've been thoroughly looking for a solution, but couldn't find out how to do it, so any ideas would really help. I would preferably use a solution that is based on the EBImage package.

推荐答案

有两种方法可以用基本图形函数排列几个图，即 par（mfrow = c（行，列））（用整数替换 rows 和 columns ）和 layout（mat）其中 mat 是一个矩阵，如矩阵（c（1,2,3） ，4））。

如需了解更多信息，请参阅？par ，？layout ，尤其是 Quick-R：合并图表。

There are two ways how to arrange several plots with base graph functions, namely par(mfrow=c(rows,columns)) (substitute rows and columns with integers) and layout(mat) where mat is a matrix like matrix(c(1,2,3,4)).
For further info see ?par, ?layout, and especially Quick-R: Combining Plots.

然而，由于您的问题是关于图像，我不知道它是否对您有所帮助。如果没有，我很抱歉误解你的问题。

However, as your question is about images I don't know if it helps you at all. If not, I am sorry for misinterpreting your question.
