Generating a complex table of drug, disease, and phase
Synopsis of Problem:
- Trying to create a table which lists the drugs and diseases for a given phase or combination of phases of a clinical trial (I, II, II).
- Data structure: Each observation has a given drug, disease, and phase. For each drug, there could be multiple diseases and/or phases.
The attached files give
possible solutions:
- Possible Solution 1 (Theresa Scott):
- Possible Solution 2 (Jeremy Stephens):
- drugs.r: R Code
- Will produce the following data frame (newx) based on the test data:
Drug Phase Disease
1 A III Healthy Normal
2 B II Rheumatoid Arthritis
3 B I Healthy Normal,Rheumatoid Arthritis
4 C I Osteoarthritis
5 D II Depression
6 D III Healthy Normal
7 E I Venous Ulcers
8 F I Venous Ulcers
9 G II Anxiety
10 G III Depression
11 G I Healthy Normal
12 H II Rheumatoid Arthritis
13 I II Asthma
14 I I Hypertension
15 J II Osteoarthritis
16 K I Asthma
17 K III Chronic Pulmonary Disease
18 K II Asthma
19 L III Prostate cancer
20 L II Prostate cancer
21 M I Obsessive Compulsive Disorder
22 M III ADHD
23 M II Obsessive Compulsive Disorder
24 N III Diabetes
Haven't worked out how to put it in a format like
I II II
Drug
Yet, but that'll be next along with the
Phase Drug Disease
I A ..., ...
B ..., ...
C etc.
II D
E
F
III G
H
I
format.
