Hello,
Is there any simple command to write the data.frame to the file in the
format of command line input?
For example, I read a table as
> data <- read.table()
and want to write out the 'data' object into my R file as
data <- data.frame( some.column1=c( 1, 2 ),
some.column2=c( 1, 2 )
row.names=c("row name1", "row name2" )
so I don't have to type the data again in my library file to provide
demos.
Thank you, in advance.

If you want to avoid it, you can assign the data.frame to a variable name (the name "data" isn't a good idea, because data() is already a function) as you described above, e.g. put it in a file "zzz.R". This is described exactly in the manual "Writing R Extensions" in chapter 1, particularly see section 1.1.3.

You could also use save() to save an R binary file -- these are compatible across platforms and are compressed to take up less space than dump()s. -thomas -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
