已在for循环中创建的多个ggplot2图的网格 [英] Grid of multiple ggplot2 plots which have been made in a for loop

问题描述

作为一个新的ggplot2用户，我有点迷失了很多可能性，并且很难在网上找到我认为是一个简单问题的简单答案。

我想在同一张纸上显示ggplot2的多个图表，但知道这些图表来自for循环。

以下示例不编译，它只是为了说明：

  for（i in c（1：n））{
 for（j in c （1：m））{
 ..........＃一些数据产生
p < -  ggplot（df.all）+ geom_bar（aes_string（x = class.names [i ]，fill = var.names [j]）
}} 
  

覆盖，但我想有一个矩阵或一个列表，我可以把所有的p，因为它们是生产，然后一个简单的函数，如

  display_in_a_grid（list_of_ggplot_plots）
  

但据我所知，我无法列出阴谋矩阵，既不是找到一个只需要一个参数输入的函数。

关于我看过的东西：

来自package gridExtra的arrangeGrob不起作用，因为它需要每个plot的明确名称（例如：p1，p2，p3，...），如 http://code.google.com/p/gridextra/wiki/arrangeGrob

facet方法不适用于我的数据集的组织（或相反：p）

您是否有简单的方法来管理它？

解决方案我会倾向于同意Richie，但是如果你想自己安排它们：

  library（ （i在1：4中）{
p [[i]] < -  qplot（1:10）的
库（ggplot2）
p < ，10：1，main = i）
} 
 do.call（grid.arrange，p）
  

需要一个厕所k在的结尾处的例子中？arrangeGrob 用于消除for循环的方法：

  plots = lapply（1：5，function（.x）qplot（1：10，rnorm（10），main = paste（plot，。x）））
 require（gridExtra ）
 do.call（grid.arrange，plots）
  

as a new ggplot2 user, I am a bit lost with the amount of possibilities, and struggle to find on the net a simple answer to what I consider a simple problem.

I would like to display multiple plots from ggplot2 on a same sheet, BUT knowing that these plots come from a for loop.

Following example does not compile, it is only to illustrate :

for(i in c(1:n)){                                   
  for(j in c(1:m)){
    ..........  # some data production
    p <- ggplot(df.all) + geom_bar(aes_string(x=class.names[i],fill=var.names[j])
}}

Here, p is overwritten, but I would like to have instead a matrix or a list in which I can put all the p as they are produced, then a simple function like

display_in_a_grid(list_of_ggplot_plots)

But as far as I tried, I was not able to make a list of matrix of plot, neither to find a function that takes only one argument for input.

About things I have had a look at :

"arrangeGrob" from package gridExtra doesn't work because it requires an explicit name for each plot (e.g.: p1,p2,p3,...) like in http://code.google.com/p/gridextra/wiki/arrangeGrob

"facet" method of ggplot2 is not adapted to the organization of my data set (or the contrary :p )

Would you have a simple way to manage this ?

Thank you,

François

解决方案

I would be inclined to agree with Richie, but if you want to arrange them yourself:

library(gridExtra)
library(ggplot2)
p <- list()
for(i in 1:4){
  p[[i]] <- qplot(1:10,10:1,main=i)
}
do.call(grid.arrange,p)

take a look at the examples at the end of ?arrangeGrob for ways to eliminate the for loop altogether:

plots = lapply(1:5, function(.x) qplot(1:10,rnorm(10),main=paste("plot",.x)))
require(gridExtra)
do.call(grid.arrange,  plots)
