I wish to rearrange the matrix, df, such that all there are not repeated x
values. Particularly, for each value of x that is reated, the corresponded y
value should fall under the appropriate column. For example, the x value 3
appears 4 times under the different columns of y, i.e. y1,y2,y3,y4. The output
should be such that for the lone value of 3 selected for x, the corresponding
row entries with be 7 under column y1, 16 under column y2, 12 under column y3
and 18 under column y4. This should work for the other rows of x with repeated
values.
df
x y1 y2 y3 y4
1 3 7 NA NA NA
2 3 NA 16 NA NA
3 3 NA NA 12 NA
4 3 NA NA NA 18
5 6 8 NA NA NA
6 10 NA NA 2 NA
7 10 NA 11 NA NA
8 14 NA NA NA 8
9 14 NA 9 NA NA
10 15 NA NA NA 11
11 50 NA NA 13 NA
12 50 20 NA NA NA
The output should be:
x y1 y2 y3 y4
1 3 7 16 12 18
2 6 8 NA NA NA
3 10 NA 11 2 NA
4 14 NA 9 NA 8
5 15 NA NA NA 11
6 50 20 NA 13 NA
Can any write for me a code that would produce these results.
Thank you in advance for your help.
