ID   Diag   Proc  DOB  Gender   
a    diag1    1   10/15/1969 M  
b    diag2    2    8/25/1978 F
c    diag1    1    1/10/1985 M 
a    diag3    3    10/15/1969 M
b    diag4    4    8/25/1978 F
b    diag4    5    8/25/1978 F
",sep="",header=TRUE,stringsAsFactors=FALSE)
library(reshape)
res<-reshape(dat1,idvar=c("ID","DOB","Gender"),v.names="Diag",timevar="Proc",direction="wide")
 res
#  ID        DOB Gender Diag.1 Diag.2 Diag.3 Diag.4 Diag.5
#1  a 10/15/1969      M  diag1   <NA>  diag3   <NA>   <NA>
#2  b  8/25/1978      F   <NA>  diag2   <NA>  diag4  diag4

Hello,

I have a data which looks like below: Some of the patients have multiple diagnosis.

ID(200 patients)   Diag (100 unique Diag-200 in general)   Proc (50 uniqe Proc)  DOB (200)   Gender (200)   
a                           daig1
b                           diag2
c                            diag1

I want to reformat this data to :

ID   diag1 diag 2 diag 3..  diagx   proc1   proc2   proc3... procx  DOB  Gender
