本文介绍了线条图组的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我有以下数据,我想创建一个有条件的线图,条件是 group1 和 group2 变量。 dat .Label = c(a,b), class =factor), group2 = c(1L,2L,3L,4L,1L,2L ,3L), val1 = c(10L,3L,2L,7L,10L,3L,2L), val2 = c(8L,4L,8L,5L,8L,4L,8L), val3 = c(7L,5L,6L,9L,7L,5L,6L)), .Names = c(group1,group2,val1,val2 val3), class =data.frame,row.names = c(NA,-7L)) 理想情况下,我想有两张基于 group1 的图(两个用于 a 和 b )以及每个组中 1变量我需要基于t的折线图他行变量(基本上连接三个点为 val1 , val2 和 val3 group2 变量,使用不同的颜色来创建c $ c>)。 >你的意思是这样的: dat2 group2 =因子(rep(group2,each = 3)), values = stack(dat [,3:5])[,1])) 上面的代码将数据重构为更容易与ggplot一起使用的格式。 dat 是使用添加到您的Q中的 dput()代码定义的。我认为您想要的图可以生成通过 p geom_point()+ facet_wrap(〜group1,ncol = 2)p 给出 我基本上不得不补充一些 x 数据,否则你怎么知道x - 这些点应该位于哪个y坐标空间? I have the following data and I want to create a line chart conditional on group1 and group2 variable.dat <- structure(list(group1 = structure(c(1L, 1L, 1L, 1L, 2L, 2L, 2L), .Label = c("a", "b"), class = "factor"), group2 = c(1L, 2L, 3L, 4L, 1L, 2L, 3L), val1 = c(10L, 3L, 2L, 7L, 10L, 3L, 2L), val2 = c(8L, 4L, 8L, 5L, 8L, 4L, 8L), val3 = c(7L, 5L, 6L, 9L, 7L, 5L, 6L)), .Names = c("group1", "group2", "val1", "val2", "val3"), class = "data.frame", row.names = c(NA, -7L))Ideally, I want to have two graphs based on group1(two for levels a and b) and within each group1 variable I need line charts based on the row variables(basically connecting three points for val1, val2, and val3) with different colors for different group2 variables. 解决方案 Do you mean something like this:dat2 <- with(dat, data.frame(group1 = rep(group1, each = 3), group2 = factor(rep(group2, each = 3)), values = stack(dat[,3:5])[,1]))The above code restructures the data into a format more easily used with ggplot. dat was defined using the dput() code I added to your Q. The plot I think you want can be produced viap <- ggplot(dat2, aes(x = 1:3, y = values, colour = group2)) + geom_line() + geom_point() + facet_wrap(~ group1, ncol = 2)pwhich givesI've basically had to make up some x data otherwise how do you know where in the x- and y-coordinate space the points should be located? 这篇关于线条图组的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
