Hello Everyone,
I am trying to create a subset of a data frame (df1) based on the first
three
unique values in the first column (v1).
Here are my codes:
b <- unique(df1$v1)[1:3]
df2 <- subset(df1,df1$v1==b)
df1:
v1 v2 v3
1 a b
1 a1 b1
2 a2 b2
2 a3 b3
3 a4 b4
3 a5 b5
3 a6 b6
4 a7 b7
4 a8 b8
4 a9 b9
5 a10 b10
5 a11 b11
5 a12 b12
5 a13 b13
Ideally, I want my new dataframe (df2) to look something like this:
df2:
v1 v2 v3
1 a b
1 a1 b1
2 a2 b2
2 a3 b3
3 a4 b4
3 a5 b5
3 a6 b6
However, that doesn't seem to be the case and i am getting the following
warning message:
Warning message:
In df1$v1==b : longer object length is not a multiple of shorter object
length
I would appreciate any help in this regard,
sincerely,
bhaskar
