I'm new to R and I'm struggling with some datasets....
I have two datasets - dataset A includes x(depth) and y(concentration) and dataset B includes x(depth) and y(age).
In dataset A, my depth is evenly spread out, such as
Depth(cm) Concentration(ppm)
1 100
2 110
3 112
4 95
5 29
6 40
7 20
8 114
9 92
10 93
and so on.
But in my dataset B, my depth is spaced out irregularly, such as
Depth (cm) Age(year)
1 10
3 19
7 32
In this case, would it be possible to extract columns with depths of dataset B (at 1, 3, 7cm) from dataset A, so that I'll get something like below as a result?
Depth (cm) Concentration (ppm)
1 100
3 112
7 20
