R - create a Panel dataset from 2 Cross sectional datasets

Could you please help me with the following task of creating a panel dataset from two cross-sectional datasets?

Specifically, a small portion of the cross-sectional datasets are:

1) - data1

  ID| Yr    | D | X
 -------------------
 1  | 2002  | F | 25    
 2  | 2002  | T | 27

& 2) - data2

ID  | Yr   | D  | X 
---------------------
1   | 2003 | T  | 45    
2   | 2003 | F  | 35

And would like to create a panel of the form:

ID  | Yr   |    D   | X 
----------------------- 
1   | 2002 |    F   | 25    
1   | 2003 |    T   | 45    
2   | 2002 |    T   | 27    
2   | 2003 |    F   | 35

The codes I have tried so far are:

IDvec<-data1[,1]

ID_panel=c()
for (i in 1:length(IDvec)) {
   x<-rep(IDvec[i],2)
   ID_panel<-append(ID_panel,x)
}

Years_panel<-rep(2002:2003,length(IDvec))

But cannot quite figure out how to link the 3rd and 4th columns. Any help would be greatly appreciated. Thank you.

Assuming that you want to concatenate data frames, then order by ID and Yr. Here's a dplyr approach:

library(dplyr)
data1 %>%
  bind_rows(data2) %>%
  arrange(ID, Yr)

  ID   Yr D  X
1  1 2002 F 25
2  1 2003 T 45
3  2 2002 T 27
4  2 2003 F 35
