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.

History

#1 Updated by Dan Higgins over 13 years ago

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.

#2 Updated by Dan Higgins over 13 years ago

for array outputs from RExpression actor, the 'NA' values are converted to 'nil'
values in current version (1Mar2006). Strings, doubles not yet handled correctly.

#3 Updated by Dan Higgins over 13 years ago

RExpression actor support for nils has been completed

#4 Updated by Redmine Admin over 6 years ago

Original Bugzilla ID was 2375
