R attenu Joyner-Boore 衰减数据

说明

该数据给出了加利福尼亚州 23 次地震的各个观测站测量的峰值加速度。这些数据已被许多工作人员用来估计距离对地面加速度的衰减影响。

用法

attenu

格式

包含 5 个变量 182 个观测值的 DataFrame 。

[,1]	event	numeric	活动编号
[,2]	mag	numeric	力矩大小
[,3]	station	factor	电台编号
[,4]	dist	numeric	Station-hypocenter距离(公里)
[,5]	accel	numeric	峰值加速度(g)

例子

require(graphics)
## check the data class of the variables
sapply(attenu, data.class)
summary(attenu)
pairs(attenu, main = "attenu data")
coplot(accel ~ dist | as.factor(event), data = attenu, show.given = FALSE)
coplot(log(accel) ~ log(dist) | as.factor(event),
       data = attenu, panel = panel.smooth, show.given = FALSE)
