RExpression support for nil tokens
Added by Dan Higgins about 18 years ago.
Updated about 18 years ago.
Description
Missing values support is being added to Kepler/Ptolemy by use of 'nil' values.
The RExpression actor needs to be able to handle 'nils' and convert to R 'NA'
values.
RExpression actor has already been modified to handle nils on input ports. (This
occurs thru the use of a 'nil' -> 'NA' conversion based on string substitution
(since all input conversion is thru strings).
Currently (3/1/2005) conversion of output (NA -> nil) needs to be handled.
for array outputs from RExpression actor, the 'NA' values are converted to 'nil'
values in current version (1Mar2006). Strings, doubles not yet handled correctly.
RExpression actor support for nils has been completed
