Hello, suppose I have a data frame:
> mat id age 1 NA NA 2 NA NA 3 NA NA 4 NA NA 5 NA NA Then I attach the data frame: > attach(mat) I assign some new values... > id <<- sample(100,5) > age <<- rnorm(5,mean=30) Then I want to create a new data frame from the variables id and age which still are attached to position 2 of the R environment... > new_mat <- data.frame(ls(pos=2)) # I want to rescue ALL variables that were > created by attach(mat) > new_mat ls.pos...2. 1 age 2 id But this leads to a bogus object... how can I rescue the updated id and age values into new_mat?
