R attenu Joyner-Boore 衰減數據

說明

該數據給出了加利福尼亞州 23 次地震的各個觀測站測量的峰值加速度。這些數據已被許多工作人員用來估計距離對地麵加速度的衰減影響。

用法

attenu

格式

包含 5 個變量 182 個觀測值的 DataFrame 。

[,1]	event	numeric	活動編號
[,2]	mag	numeric	力矩大小
[,3]	station	factor	電台編號
[,4]	dist	numeric	Station-hypocenter距離(公裏)
[,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)
