[R] About multiple panels with limited space in-between

[lily li]

Hi R users,

I have a question about plotting. The following two datasets are an
example. What I have in mind is like the attached figure, but just have two
rows, top row is for DF1, bottom row is for DF2. The top and bottom rows,
have x-axis as var1, var2, var3, etc, while the y-axis represents A. For
each row, only the leftmost panel has y-axis ticks and label. For the two
rows, only the bottom row has x-axis ticks and label. I am not very clear
about the coding. Thanks if you could give me any suggestions.


DF1: Year 2000
A     var1   var2   var3   var4   var5
1.2   0.8     0.9     1.1     1.2     12
1.8   0.9     1.2     1.0     2.1     15
1.5   0.7     1.1     0.9     2.2     16
1.6   0.9     1.0     0.7     2.5     18

DF2: Year 2001
A     var1   var2   var3   var4   var5
1.1   0.85     0.9     1.1     1.2     22
1.4   0.99     1.2     1.0     2.1     25
0.8   0.74     1.1     0.9     2.2     26
0.6   0.92     1.0     0.7     2.5     28
