Dear R-help list,
Apologies. I am trying to convert one table to another. It feels that it
should be a very straightforward answer with a single (or two) commands with
the right extensions, but I really can't figure this out right now. I have
several hundred pheno factors actually, so manually doing this line by line
is not an option.
My original table is approximately like this :
ID pheno
1 A Breast Cancer
2 A Appendicitis
3 A Microcephaly
4 B Polyps
5 B Autism
6 C Autism
7 D Breast Cancer
8 D Polyps
9 D Appendicitis
10 E Breast Cancer
What I want is this :
ID Breast Cancer Appendicitis Microcephaly Polyps Autism A 1 1 1 B 1
1 C 1 D 1 1 E 1
The data is here
data <-
data.frame(ID=c(rep("A",3),rep("B",2),rep("C",1),rep("D",3),rep("E",1)),
pheno=c("Breast
Cancer","Appendicitis","Microcephaly","Polyps","Autism","Autism","Breast
Cancer","Polyps","Appendicitis","Breast Cancer"))
Thank you very much! Many apologies.
