] avoid losing data.frame attributes on cbind()
HI,
Not sure if this helps:
library(plyr)
res-mutate(Xa,var1=round(Sepal.Length),var2=round(Sepal.Width))
str(res)
#'data.frame':150 obs. of 7 variables:
# $ Sepal.Length: num 5.1 4.9 4.7 4.6 5 5.4 4.6 5 4.4 4.9 ...
# $ Sepal.Width : num 3.5
3 3 3 4 4 3 3 3 3 ...
# - attr(*, label)= chr Some df label

Dear Arun,

Dear all,
How should I add several variables to a data frame without losing the
attributes of the df? Consider the following:
require(Hmisc)
Xa - iris
label(Xa, self=T) - Some df label
str(Xa)
'data.frame': 150 obs. of 5 variables:
$ Sepal.Length: num 5.1 4.9 4.7 4.6 5 5.4 4.6 5 4.4 4.9
...
#- attr(*, label)= chr Some df label
A.K.

Hi,
Another method would be:
Xc- Xa
Xc$var1-NA; Xc$var2- NA
Xc
