[R] R equivalent to `estimate' in SAS proc mixed

Example: I have the following model model - lmer(response ~ time * trt * bio + (time|id), data = dat) where time = time of observation trt = treatment group (0-no treatment / 1-treated) bio = biological factor (0-absent / 1-present) and I would like to obtain an
