Splus 4.0

Note these directions are for an old version of SPlus

Using Splus 3.3 objects in Splus 4.0

In general, objects created by Splus 3.3 should be compatible with Splus 4.0.

This is the safest way to save your data and transfer it between systems.

Splus 3.3 seems to be able to use most Splus 4.0 objects.

Some other issues that may arise in using Splus 4.0

  1. <Ctrl C>.has been replaced by <ESC> as the interrupt key.
  2. <Ctrl Ins>/<Shift Ins> have been replaced by <Ctrl C>/<Ctrl V> for Copy/Paste.
  3. graphsheet() has replaced win.graph(), although the latter still works. You no longer need to explicitly open a graphics device before using a plotting function.
  4. The Object Manager in 3.3 has been replaced by the Object Browser in 4.0.
  5. There is a new data editor in 4.0.
  6. The File > File/Import and File > File/Export menus are different (different underlying software).
  7. Modules such as S+SpatialStatistics, S+Wavelets, etc., do not yet work with S-PLUS 4.0. New versions will be issued shortly.
  8. Loops no longer have a meaningful return value. In the past
    j <- 0
    x <- for(i in 1:10) j <- j + i
    would result in x==55 (same as j) but in 4.0 x will be vector("missing",0) which doesn't even get printed (j will still have the value 55).
  9. The value of source("file") is now vector("missing",0) (i.e., not meaningful) if the last expression in file is an assignment. This was to work around another bug.
