I think the OP was looking to expand the data frame so that each row was a
single observation so that the first row becomes 6 rows, 4-TRUE and 2-FALSE.
Something like this
> womensrole <- HSAUR::womensrole
> step1 <- reshape(womensrole, varying=c("agree", "disagree"),
+ v.names="Freq", timevar="Agree", times=c(TRUE, FALSE),
+ direction="long")
> step1 <- step1[order(step1$id),]
> rownames(step1) <- NULL # Simplify the row names
> step2 <- step1[rep(rownames(step1), step1$Freq), c(5, 1:3)]
> rownames(step2) <- NULL # Simplify the row names
> head(step2, 12)
id education sex Agree
1 1 0 Male TRUE
2 1 0 Male TRUE
3 1 0 Male TRUE
4 1 0 Male TRUE
5 1 0 Male FALSE
6 1 0 Male FALSE
7 2 1 Male TRUE
8 2 1 Male TRUE
9 3 2 Male TRUE
10 3 2 Male TRUE
11 3 2 Male TRUE
12 3 2 Male TRUE

Subject: Re: [R] convert data frame: two variables into _one_ binary variable
In R, as.logical() and other functions treat anything >0 as TRUE. Thus:
Rgames> foo<-sample(0:5,10,rep=TRUE)
Rgames> foo
[1] 0 5 1 0 1 5 2 5 4 5
Rgames> as.logical(foo)
[1] FALSE TRUE TRUE FALSE TRUE TRUE TRUE TRUE TRUE TRUE
For your case, simply (womensrole$agree>womensrole$disagree) will return
the logical vector you want.
Just for info,
In R, as.logical() and other functions treat anything >0 as TRUE. Thus:
Rgames> foo<-sample(0:5,10,rep=TRUE)
Rgames> foo
[1] 0 5 1 0 1 5 2 5 4 5
Rgames> as.logical(foo)
[1] FALSE TRUE TRUE FALSE TRUE TRUE TRUE TRUE TRUE TRUE
