R help - Nov 2013 - Providing a Title for a Write.Table - Thinking of Titles in SPSS CTABLES

I understand how I may use message() to provide some output on which run I will
be looking at. However, I wish to automate it, and have it written out to a
tab-delimited file. Below is the command to output my coefficients:

write.table(zbetas, file = "z_coeffs.csv", sep="\t", append
= TRUE)

I do this run multiple times. It appends the latter results to the end of my
.csv file.

Is there a way to say just before the write.table something to the effect of:

title("First Run", append = TRUE)?

Or perhaps there is a sub-command in the write.table to accomplish this.

So when I interactively run my code it could be something like:

First run
Coeff1 0.34
Coeff2 0.96

Second run
Coeff1 0.47
Coeff2 0.95

Thank you very much in advance.

One way to do it, is just to insert another write.table() command giving
the text you want to write.  Here's a simple example:

myfile <- "c:/temp/junk.csv"
for(i in 1:5) {
df <- data.frame(x=rnorm(3), y=rnorm(3))
write.table(paste0("Run #", i), myfile, sep="\t",
append=(i!=1),
col.names=FALSE, row.names=FALSE)
 write.table(df, myfile, sep="\t", append=TRUE, col.names=FALSE)
}
