Hello R users,
I have two data sets like the following. Form of dataset:
data:
X1 X2 X3 X4 X5
1902 RE 3 594 9
1903 RE 3 1340 7
1904 AA 3 760 14
1908 RE 4 1759 18
1909 EX 2 387 1
2901 AU 6 3116 2
3801 AA 1 304 29
3902 RE 5 2482 6
I need to select rows of a data set based on the common observations of X1.
Using intersect command I got the common observations of X1 from the two data
sets as:
common=c(1902, 1904, 1908, 1909, 3801).
Using subset command I can select portions separately. But in general if I am
given this type of dataset - "data" with large number of rows and also a list
of
X1 - "common" containing many elements, can anyone please let me know how to
select portion of the data whose X1 values are same as common values.
If any questions let me know.
Shant.
