lookup.xport ignores some datasets in sas export file.
File "emptySasData3.xpt"
(available at http://biostat.mc.vanderbilt.edu/tmp/emptySasData3.xpt)
is a recreation of sensitive data.
It was generated in SAS as an export file containing 51 empty datasets,
but it has a structure of the non-empty data that revealed the problem
(and can not be shared).
It means that lookup.xport ignores non-empty datasets also.
The file "emptySasData3.xpt" has 51 empty datasets.
lookup.xport reads only 37 first datasets.
(In non-empty data lookup.xport ignored
datasets in the middle (not in the end) )
> look <- lookup.xport("emptySasData3.xpt")
> names(look)

The following datasets were not read by lookup.xport
UR, URN, VIS, VIT, VO.
The example of the
SAS code used to builds the empty data
from the non-empty data in "export.xpt".
options nofmterr;
proc options;run;
libname x sasv5xpt "H:\projects\export.xpt";
libname y sasv5xpt "H:\projects\emptySasData3.xpt";
data ae; set x.ae(obs = 0); run;
...
data vit; set x.vital(obs = 0); run;
data vo; set x.volume(obs = 0); run;
proc copy in = work out = y; run;
I think I did not miss anything,
thank you,
Svetlana
