Hi again,
I have another question for different data.
Here is how my data looks like:
ID Lab Status
a 1 N
a 1 A
a 2 N
b 3 N
b 1 A
I need to reformat this data as following.
ID Lab1.N Lab1.A Lab2.N Lab2.A Lab3.N Lab3.A
a 11 1000
b 0 1001 0
Thanks a lot:)
Best,Farnoosh Sheikhi

Hi,
Is this okay?
library(reshape2)
dat1<-read.table(text="
ID Diag Proc DOB Gender
a diag1 proc1 10/15/1969 M
b diag2 proc2 8/25/1978 F
c diag1 proc1 1/10/1985 M
a diag3 proc3 10/15/1969 M
b diag4 proc4 8/25/1978 F
b diag6 proc5 8/25/1978 F
",sep="",header=TRUE,stringsAsFactors=FALSE)
res<-dcast(melt(dat1,id.var=c("ID","DOB","Gender")),ID+Gender+DOB~value)
res[,4:13]<-ifelse(is.na(res[,4:13]),0,1)
res
# ID Gender DOB diag1 diag2 diag3 diag4 diag6 proc1 proc2 proc3 proc4
#1 a M 10/15/1969 1 0 1 0 0 1 0 1 0
#2 b F 8/25/1978 0 1 0 1 1 0 1 0 1
#3 c M 1/10/1985 1 0 0 0 0 1 0 0 0
# proc5

#2 1
#3 0

Hi there,
Thanks a lot for your help, but Proc doesn't show in the result.
I also want to assign 1 and 0 instead of the name of variables.
Thanks a lot.

HI,
It is better to dput() an example dataset to work with.
May be this helps:
dat1<-read.table(text="
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
#3 c 1/10/1985 M diag1 <NA> <NA> <NA> <NA>
