在 R 中，绘制连续/顺序事件

Question

已编辑：遵循建议

我正在尝试根据这篇文章创建一个简单的连续事件频率图：ggplot sequence patterns

我想为其他主题（不同的序列）堆积相同的情节 主题"aa", "bb", "cc"

示例数据集如下：

subject <- c("aa","aa","aa","aa","aa","aa","aa", "bb","bb","bb","bb","bb","bb","bb","cc","cc","cc","cc","cc","cc","cc")
event <- c("P","C","D","C","P","E","D","C","P","E","D","P","C","E","P","E","D","P","C","x","x")
freq <- c(3,2,1,4,2,1,0,3,4,1,3,3,1,2,1,3,2,1,4,0,0))

dfx <- data.frame(subject, event, freq)

我得到的结果是：

使用此代码，基于原帖：

library(ggplot2)

dfx$type <- factor(dfx$type)
dfx$ymin <- c(0,1,2)
dfx$ymax <- c(1,2,3)
dfx$xmax <- cumsum(dfx$count)
dfx$xmin <- c(0, head(dfx$xmax, n=-1))

plot_x <- ggplot(dfx, 
            aes(xmin=xmin, xmax=xmax, ymin=ymin, ymax=ymax,fill=type))   +geom_rect(colour="grey40", size=0.5)

png("plot_x.png", height=200, width=800)
print(plot_x)
dev.off()

我已经用我想要绘制的内容创建了这个图像。 （它是用excel手工制作的）。在这种情况下，我们有 3 个主题、4 个事件（C、P、D、E）+1 个虚拟事件（X），这是创建数据框所必需的。如您所见，每个主题的事件总数不一定相等。

Answer 1

尝试使用facet_grid 或facet_wrap

library(ggplot2)
p1  <-  
    ggplot(dfx, aes(xmin = xmin, xmax = xmax, ymin = ymin, ymax = ymax, fill = event))+
    theme_bw() + 
    geom_rect(colour = "black", size = 0.5) + 
    facet_grid(subject ~ .) + 
    theme(axis.ticks.y=element_blank(), axis.text.y=element_blank())

p1

数据：

dfx <- data.frame(
       subject = c("aa","aa","aa","aa","aa","aa","aa", "bb","bb","bb","bb","bb","bb","bb","cc","cc","cc","cc","cc","cc","cc"),
       event = c("P","C","D","C","P","E","D","C","P","E","D","P","C","E","P","E","D","P","C","x","x"),
       freq = c(3,2,1,4,2,1,0,3,4,1,3,3,1,2,1,3,2,1,4,0,0),
       ymin = 0,
       ymax = 1)

TEMP        <-  tapply(dfx$freq,dfx$subject,cumsum)
dfx$xmax    <-  unlist(TEMP)
dfx$xmin    <-  c(0, head(TEMP$aa, -1), 0, head(TEMP$bb, -1), 0, head(TEMP$cc, -1))
