Hi,
How can I achieve this in R. Dataset is as follows:
>df
x
1 2
2 4
3 1
4 3
5 3
6 2
structure(list(x = c(2, 4, 1, 3, 3, 2)), .Names = "x", row.names = c("1",
"2", "3", "4", "5", "6"), class = "data.frame")
I want to recreate a new data frame whose rows are sum of (1&2, 3&4, 5&6) of
original df. For example
>newdf
x
1 6
2 4
3 5
Thanx in advance for the help.
Sachin
