Data Transfer: VARIANTs � VARIANTs can contain any data – numbers – strings (Unicode strings) – arrays/matrices of numbers and strings – objects � contents are determined by the VARIANT‘s type (VT) � most languages allow transparent use (e.g. Visual Basic 6, Visual C#) � a bit harder to use in C or C++
Data Transfer: Special Values � R‘s special values – NULL, NaN, -Inf, Inf, NA � representation in VARIANT – VARIANT type VT_ERROR – compatible with Microsoft Excel‘s representation R Value NULL NaN -Inf Inf NA converts to xlErrNULL xlErrDiv0 xlErrDiv0 xlErrDiv0 xlErrNA back to R NULL – NaN will become xlErrNum in next major release of R Inf Inf Inf NA
