I need to obtain username and password strings from the
user of a certain process running in R. scan() can be used
to get the strings, but the password will be echoed back as the
user types it. Is there any way to load keyboard input
to a variable without echoing the input back to the screen?

Luke,
My actual problem was with the RAW() macro, it is not available as a
function. I used INTEGER as an illustration because it was in the same

Thank you for your other comments. I was confused, somehow I thought
that in 2.0.x ALL access, even to the a
Your original question was about macro-like functions. INTEGER is
available to internal R code as a macro; it is also available as a
function. Code in packages that uses standard hearders will see the
function, which is declared as
int *(INTEGER)(SEXP x);
I have no idea why you wanted to check wh

Thank you to Duncan Murdoch for pointing to

What is imgSize? The behavior you describe seems as if you re-using the

Dear R developers,
I am writing some C code that loads multiple images into a list of R
matrices. The whole R object is created within the C code. To simplify
coding, elements of the list are first created as vectors and then
converted to corresponding matrices using setAttrib(x, R_DimSymbol, s)

What version of iconv -l is that produces such a list? That in glibc

Your fix is not safe: iconv in libiconv produces items se
