如何根据间隔剪切两个数据帧并合并它们？

数据框1

read.table(textConnection(
"   from to Lith  
1   0   1.2 GRN   
2   1.2 5.0 GDI   
"), header=TRUE)    

数据框2

read.table(textConnection(
"   from to Weath  
1   0  1.1  HW  
2   1.1 2.9 SW 
3   2.9 5.0 HW  
"), header=TRUE) 

产生的数据框架

  from to Weath Lith 
1 0.0 1.1 HW  GRN
2 1.1 1.2 SW  GRN
3 1.2 2.9 SW  GDI
4 2.9 5.0 HW  GDI
