R有效地计数频率

假设我有一个问题，我有一个向量，叫做，基，定义为

bases <- c(1:100000)

---

bases本质上，您是在寻找直方图。使用
hist
功能

bases <- c(1:100000)
instances <- c(12, 367, 442, 551, 1882, 2556, 13222, 13772, 
               18999, 26000, 29004, 83027)

# plot = 0 prevents plotting 
# breaks are the values at which we want to split our interval 
h <- hist(instances, breaks = seq(0, max(bases), 1000), plot=0) 

base查看
findInterval
和
cut
…可能还有
table
或
tablate
。我认为这是最有效和明智的方法，因为我计划稍后绘制直方图：）
bases <- c(1:100000)
instances <- c(12, 367, 442, 551, 1882, 2556, 13222, 13772, 
               18999, 26000, 29004, 83027)

# plot = 0 prevents plotting 
# breaks are the values at which we want to split our interval 
h <- hist(instances, breaks = seq(0, max(bases), 1000), plot=0)
