R help - Jan 2003 - Errors running R in Batch mode under Win2000

I have made many different attempts to run a R program in Batch mode. I run a
DOS command like:

C:\Progra~1\R\rw1061\bin\rterm.exe  -q --no-restore --no-save   myprogram.R 
out.txt

What happens:
1. DOS Shell starts up well
2. R starts
3. I get the messages:
    "ARGUMENT 'myprogram.R' __ignored__"
    "ARGUMENT 'out.txt' __ignored__"
4. R Shell is ready to roll (which is nice, but not what I intended to get)

Help is greatly appreciated: how can I start myprogram.R?

See the R for Windows FAQs, Section 2.9: "Can I use R BATCH?"

Uwe Ligges

See the rw-FAQ.  Please do check the FAQs before posting.

This is not how you start any C program in batch mode under any OS I am
aware of, and certainly not under Windows.  You need to learn about
redirection (< and >).

I am trying (I think) to achieve something like "sweep" for data
frames.

I have a data frame. Two columns are factors, say with L and M levels; one
is numeric. Within each of L*M classes of observations, I would like to
normalize the numerical value by its mean.

Here is an example of what I mean.

data <- data.frame(
  
fac1=c("A","A","B","B","B"),
  
fac2=c("a","b","a","a","b"),
   x=rnorm(5))
split.names <- c("fac1","fac2")
t <- tapply(data$x, data[split.names], mean)
# now t is an array, and I can index it like this:
t["A","b"]
# I want to do something like
data$xnorm <- data$x / t[data[split.names]]
# but I am told: Error: invalid subscript type

I would like to retrieve a vector of the values of the t-array, one item
in the vector for each row of the data frame. I would be grateful for
instructions.

I think I could also achieve this by creating a data frame instead of the
table t, as in Venables+Ripley MASS (4th ed) p. 39, and then merging the
tables, as on p. 35. Is this the most effective way to achieve what I
want, or is there a more direct way?
