从移动范围数据中的R

Question

平均我有一系列下面显现时间范围（注意y轴并不重要）的。我想“平滑”这个数据，因此，对于任何沿x轴给出时间，我知道有多少段跨越那一刻。我发现了几篇关于如何计算R中移动平均数的文章;但是，它们都基于时间序列数据。我寻求如何总结我的数据是在“开始”和“停”的格式转换成'的形式，在时间（x）的有跨越那个时间Y事件的意见。

这里是样本数据集上面绘制：

Answer 1

也许你可以建立在这样的：

library(ggplot2) 
library(data.table) 
library(cowplot) 

range <- range(d3[-1]) 
dt1 <- data.table(start = floor(seq(range[1], range[2]+1, 1)))[,end := start + 1] 
setkey(dt1, start, end) 
dt2 <- data.table(start = d3$med2, end = d3$med1) 
dt <- foverlaps(dt2, dt1)[,.N,by="start"] 

p1 <- ggplot(d3, aes(x=med1,xend=med2,y=y,yend=y)) + geom_segment() 
p2 <- ggplot(dt, aes(x=start, y=N)) + geom_line() 
plot_grid(
    p1 + xlim(0,4500), 
    p2 + xlim(0,4500), 
    ncol = 1, align = "h" 
) 

Answer 2

这里有一个答案，使用只有base命令。

rr <- range(d3) 
bb <- seq(floor(rr[1]),ceiling(rr[2])) 
mm <- apply(d3[,-1],1,function(x) bb %in% seq(floor(x["med2"]),ceiling(x["med1"]))) 
events_at_t <- apply(mm,1,sum) 
plot.ts(events_at_t, ylab="Count")
