The SweaveInput directives are processed before any expressions are
evaluated, so you can't do it that way. You can have Sweave chunks emit
LaTex code, so this might achieve a similar effect:
<<results=tex>>=
if ( test ) name <- "my1"
else name <- "my2"
Sweave( paste0(name, ".Rnw") )
paste0("\\input{", name, ".tex}")
@
I've never tried having a Sweave chunk call Sweave(), so there might be
troubles there, and you might only be able to input .tex files, not Rnw
files.
