R help - Apr 2005 - window closed

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(...)
> time<-gam["V4"]
> status<-gam["V5"]
> fit<-survfit(Surv(time,status),data = as.data.frame(gam),
conf.type="none")

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...

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.

There's no survfit() in base R.  If you are using a contributed package,
please state it.

Please do.
