[R] bug in R BATCH with Linux?

[Christian Posse]

dear R fans,

Has anyone encountered problems when using
R BATCH  under Linux (I have Red Hat 5.2 if
that matters) ?

I have a file that works fine if I copy-paste it
interactively in a R session. However R
complains right away when I try to run the file in
batch  mode. This problem is not inherent to  R 0.64.1 I
am using now. I had the same problem with previous
releases. Also I am not using an RPM version.
R was compiled with gcc 2.7.2.3.

It is not  systematic. For example, the following
trivial example works fine:

file example:
x <- rnorm(10)
y <- 2*x + 1 + rnorm(x,0,0.1)
thefit <- lsfit(x,y)

%  R BATCH example example.out
% more example.out

The cases I remember having problems with include
a read.table. This might be the source of the problem.
I dunno.


Thanks for any help.
