Try this:

> subj1 <- cbind(-4, -3, -1, -5, -7)
> subj2 <- cbind(-2, -1, -1, -2, +2)
> subj3 <- cbind(+2, +1, +2, +1, +2)
> subj4 <- cbind(-4, -1, -2, +2, +1)
> mydf <- as.data.frame(rbind(subj1, subj2, subj3, subj4))
> mydf
  V1 V2 V3 V4 V5
1 -4 -3 -1 -5 -7
2 -2 -1 -1 -2  2
3  2  1  2  1  2
4 -4 -1 -2  2  1
> apply(mydf, 1, function(x)all(x>-3) & all(x < 3))
[1] FALSE  TRUE  TRUE FALSE
> mydf[apply(mydf, 1, function(x)all(x>-3) & all(x < 3)),]
  V1 V2 V3 V4 V5
2 -2 -1 -1 -2  2
3  2  1  2  1  2
