--------------- start of code
library(survival)
liver <- scan("liver2.txt",list(age=0,albumin=0,alkphos=0,ascites=0,bili=0,
cholest=0,edema=0,edmadj=0,hepmeg=0,obstime=0,platelet=0,protime=0,
sex=0,sgot=0,spiders=0,stage=0,status=0,treatmnt=0,
triglyc=0,urinecu=0))
fit<-coxph(Surv(obstime,status)~bili+edmadj+albumin+protime+age,data=liver)
summary(fit)

Reading in tab (and space) delimited data within a script XXXX
...d.table( textConnection(mystring),
header=TRUE, sep=",",
row.names="id", na.strings=" ")
closeAllConnections()
mydata
Can anyone suggest a similar approach for reading in tab-delimited or
single space delimited data? Example data:
data3<-
"OBSNO AGE SEX ALKPHOS LAB CAMMOL PHOSMMOL AGEGROUP
21 76 M 84 5 3.2 0.9 3
22 76 M 5 2.18 0.84 3
23 68 M 82 5 2.15 0.52 1
24 69 M 84 5 2.3 1.36 1
25 76 F 100 3 25.3 1.07 3
26 70 F 90 3 20 0.97 2
27 71 F 109 3 22.3 0.94 2
28 70 -99 65 3 24.3 1.42 2
29 74 F 61 3 25 0.87 2
30 74 F 62 3 23.3 0.94 2"
Thanks!
