我有一组测井数据.在工业中,有专门的软件来生产典型的钻孔测井图.这是一个简化的:

令人兴奋的事情是:
因为这是一个非常传统的行业,我想用我的软件(我没有专业的东西,作为学生)密切复制这些图的格式.我已经使用ggplot在路径上走了一段路,但我不知道如何做一些事情.为了解决问题,这里有一些示例数据和代码:
log <- structure(list(Depth = c(282.0924, 282.2448, 282.3972, 282.5496,
282.702, 282.8544, 283.0068, 283.1592, 283.3116, 283.464, 283.6164,
283.7688, 283.9212, 284.0736, 284.226, 284.3784, 284.5308, 284.6832,

我不知道如何:
欢迎任何帮助.
我不知道如何:
- 将两个变量组合在一个方面,并成功管理范围
我的回答仅涉及您的第一个要点的第一部分。
该colsplit()功能对于此类情况很有用。假设多个井 仪器的变量名称类似于FOO_1, FOO_2, BAR_1,BAR_2对于测量变量以及井仪器FOO1BAR和2 ,那么您可以在 ing之后调用,将适当的结构添加回您的熔化数据框架中。colsplitmelt
