omitting columns from a data frame
Dear R People:
I have a data frame, xm1, which has 12 rows and 4 columns.
If I put is xm1[,-4], I get all rows, and columns 1 - 3, which is as
it should be.
Now, is there a way to use the names of the columns to omit them, please?
Thanks so much in advance!
Sincerely,
Erin

It looks good. but when I tried to startup the guests, I got error:
sudo xm create xm1
Using config file "./xm1".
Error: (22, ''Invalid argument'')
Any ideas?
Thanks,

predict with arima0
Dear R People:
I'm trying to use the predict command on an arima0 object.
I do the following:
xm.arma <- arima0(xm2,order=c(1,0,1))
predict(xm.arma,n.ahead=2)
and I get the message:
Error in round(x, digits) : Non-numeric argument to mathematical function
Any ideas what the problem might be, please?
R version 1 4 1 on Windows.
Thanks in advance!

Passing a string variable to Surv
Hi,
I am trying to write a function to automate multiple graph
generation. My data looks like:
Table of numeric values with the following headers:
timeM1 statusM1 xM1 timeM2 statusM2 xM2 timeM3 statusM3 xM3

Where M1,M2, M3 hve no similarity except they have a max string length
of 7. Examples are mcw0045, adl0003, lei0101.
Now, what I want to do is
Function(M1, M2, M3, datafile)
{
xnew <- readtable(datafile)

summary on predict with arima0
Here is the summary on predict when
using an arima0 object:
The arima0 object must be based on a time series vector.
That is;
x <- ts(xm1, frequency=12, start=c(1975,1))
x.ar <- arima0(x,order=c(1,1,1))
predict(x.ar,n.ahead=3)
Thanks so much to Prof. Brian Ripley and David Brahm and other!
Sincerely,
Erin Hodgess
