Hi All,
Assume that I have the following data set with two variables and I
want count the number of observation with identical values and number
of time each factor changed from x1 to x2.
x1 x2
1 1
1 0
0 1
0 1
0 0
1 1
0 1
The output should be
x1 changed
0 3 # has changed 3 times
1 1 # has changed 1 time
x1 unchanged
0 1 # has unchanged only 1 time
1 2 # has unchanged 2 times
Can someone help me how to do it in R?
Thanks in advance
