[R] 'Rscript -e' and stdout() puzzle

[Benjamin Tyner]

Hello,

I am curious to know why the output of

    Rscript -e "cat(R.version.string,stdout())"

includes a trailing " 1", whereas

    Rscript -e "cat(R.version.string)"

does not. I have tried various mechanisms to subvert this behavior, such as

    Rscript -e "invisible(con<-stdout()); cat(R.version.string, con);
    rm(con); q()"

but the trailing " 1" remains.

Thanks,
Ben
