Dear R Gurus: I would like to set the number of commands in the history file as 50 rather than 25. I would do this in the .First function. How do I set this, please? I tried history(max=50) and it prints what it has. I just want to set the size in .First. Thanks in advance, Sincerely, Edna

That is the default value of max.show, not of the size of the file.> I would do this in the .First function. > > How do I set this, please?

You failed to follow the posting guide and tell us *anything* about your OS etc. But probably ?history tells you how to set the size of the history file via environment variable R_HISTSIZE.> I just want to set the size in .First. > > Thanks in advance, > Sincerely, > Edna > > ______________________________________________ > R-help at r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.PLEASE do. -- Brian D.
