thanks in advance
What do you expect as result? One observation for each "subject" with all not missing values?
this how the output should look like
subject | SODIUM_NLOW_VA | SODIUM_NHIGH_VA | POTASSIU_NLOW_VA | POTASSIU_NHIGH_VA | CARBDIOX_NHIGH_VA | CHLORIDE_NLOW_VA | CHLORIDE_NHIGH_VA | CARBDIOX_NLOW_VA |
1330 | 50 | 30 | 20 | 18 | ||||
1330 | 50 | 30 | 20 | 15 | ||||
1330 | 80 | 63 | ||||||
1330 | 80 | 63 | ||||||
1330 | 53 | 23 | ||||||
1233 | 53 | 23 |
Why should the two first obs of POTASSIU_NLOW_VA still be missing? Please provide a clear logic.
