[英]How to: Create a plot for 3 categorical variables and a continuous variable in R?
我想使用 R 创建一个 plot,最好使用 ggplot。 我有以下变量要可视化,其中大部分是二进制的:
试用:cong/incon
造句:他/他自己
状态:正常/慢
准确度:数字
SE:数字
structure(list(TrialType = structure(c(1L, 1L, 1L, 1L, 2L, 2L,
2L, 2L), .Label = c("congruent", "incongruent"), class = "factor"),
SentenceType = structure(c(1L, 1L, 2L, 2L, 1L, 1L, 2L, 2L
), .Label = c("him", "himself"), class = "factor"), Condition = structure(c(1L,
2L, 1L, 2L, 1L, 2L, 1L, 2L), .Label = c("normal_speech",
"slow_speech"), class = "factor"), MeanAccuracy = c(0.794871794871795,
0.762820512820513, 0.967948717948718, 0.967948717948718,
0.237179487179487, 0.342105263157895, 0.942307692307692,
0.83974358974359), SE = c(0.0342056016493384, 0.0430264468743046,
0.0389087806837746, 0.0496183045476835, 0.0135583881898854,
0.0163760608630386, 0.0170869868584354, 0.0311270245470197
)), class = "data.frame", row.names = c(NA, -8L))
SE 代表标准误差,这意味着我想在准确度分数周围呈现误差线。
我认为我最好的选择是制作两个条形图,每个条件分别一个,在 x 轴上具有准确性。 然后,四个条形代表句子和试验的两种可能组合,显示高度的准确性,并在此周围显示误差条以反映不确定性。
我怎么能做出这样的图表? 或者,有没有人认为这不是正确的图表类型,然后会是什么(以及如何 plot 它......)?
提前致谢!
根据您分享的描述使用一些模拟数据,您可以尝试:
library(ggplot2)
library(dplyr)
library(tidyr)
#Data
df <- data.frame(Trial=rep(c('cong','incong'),4),
Sentence= rep(c('him','himself'),4),
Condition=rep(c('normal','slow'),4),
Accuracy=runif(8,0,1),
SE=runif(8,0,10),stringsAsFactors = F)
#Plot 1
df %>% pivot_longer(-c(Trial,Sentence,Condition)) %>%
ggplot(aes(x=name,y=value,fill=Condition))+
geom_bar(stat = 'identity')+
facet_wrap(.~Trial+Sentence,scales = 'free')
Output:
或这个:
#Plot 2
df %>% pivot_longer(-c(Trial,Sentence,Condition)) %>%
ggplot(aes(x=name,y=value,fill=Condition))+
geom_bar(stat = 'identity')+
facet_grid(Trial~Sentence,scales = 'free')
Output:
了解您的问题需要更多详细信息和数据。
您是否正在寻找类似的东西?
library(ggplot2)
ggplot(df, aes(TrialType, MeanAccuracy, fill = SentenceType)) +
geom_col(position = position_dodge(width = 1), color = "gray50") +
geom_errorbar(aes(ymin = MeanAccuracy - SE,
ymax = MeanAccuracy + SE), width = 0.25,
position = position_dodge(width = 1)) +
scale_fill_manual(values = c("gold", "deepskyblue4")) +
facet_grid(.~Condition, switch = "x") +
theme_bw() +
theme(strip.placement = "outside",
strip.background = element_blank(),
panel.border = element_blank(),
panel.spacing = unit(0, "points"),
axis.line = element_line())
