I fully agree with the backwards-compatibility requirement.
Because I have to use SPSS everyday (for 'compatibility' reasons at work) I
read.spss() very often. I have one suggestion for further improvements of
I work on quite large data files (1600 vars, 10000 cases), which cannot be
loaded to R because of
lack if memory. It would be very usefull to be able to 'browse' SPSS files
'variablewise'. That is
for example to 'extract' only a group of variables (even a single one)
without loading the whole data.
Making a bunch of smaller files in SPSS and than importing them to R with
What do You think of such an improvement?
On www.spss.com I came across of an spssI/O library which is free and (as is
written in attached manual)
contains function for SPSS data files manipulation.
I would gladly do sauch a function by myself, but I do not know C at all.
