Hi R users!
Does anyone know command similar to cbind for adding a column to a
object of
the list. For example on this list:
c1
$`1`
x11 x22
1 1 1
2 1 2
3 1 3
4 1 4
5 1 5
So item `1` is probably a data.frame.
$`2`
x11 x22
6 2 6
7 2 7
8 2 8
9 2 9
10 2 10
11 2 11
i would like to add column, named random created with - runif(5)-,
to the
first object in order to obtain something like this:
c1
$`1`
x11 x22 random
1 1 1 0.5624256
2 1 2 0.6752097
3 1 3 0.1005275
4 1 4 0.3325556
5 1 5 0.7650282
Try c1[[1]] <- cbind(c1[[1]], runif(5))
(Untested. I supposed you could argue that you had provided a
reproducible example, but going through the hoops of creating two such
dataframes and then creating a list to hold them seems something that
you should have provided code for rather than posting just console
output.)
