Hello,
The editor of R will close after I enter the following
commands. I do not know the reason at all. When does this
happen? I would very appreciate it if you could let me know.
Sincerely.

gam <- matrix(scan("C:/Documents and Settings/Yoko
N/Desktop/R/sas2.txt"), ncol = 29)
Read 384132 items
Warning message:
Replacement length not a multiple of the elements to replace
in matrix(...)
scan() read 384132 items from the file. Is that the correct number that should be read in? If so, you have a problem: You've got 13245.93 rows of data in 29 columns...
time<-gam["V4"] status<-gam["V5"]
At this point "gam" is suppose to be a _matrix_, and I don't think you want to subset a matrix like that. Do you really mean to use "gam" as a data frame? If so, either read it in as a data frame, or convert to one afterward.
fit<-survfit(Surv(time,status),data = as.data.frame(gam),
conf.type="none")
There's no survfit() in base R. If you are using a contributed package, please state it.
PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
Please do. Andy
