You need to project your coordinates before you export the data to Splus.
Then your distances should be equal in Splus and ArcView. There isn't really
any issue about a different concept of coordinates in ArcView and Splus.

Subject: centroids from ArcV to S-plus
| Dear S-plus users,
|
|
| I imported two columns from an ArcView table to .pdf.
| and
| from .pdf to s-plus.
|
| The columns are the longitude and latitude of 78 municipalities of Puerto
| Rico.
| If I calculate the distance between centroids in Arc View are not the same
| as the ones calculated in s-plus using the distance decay procedure from
| spatial stats.
|
| How can I make s-plus understand Arc View information?
| Or
| How Can I transform coordinates to northing and easting?
| Or
| Any other suggestion?
|
| I will appreciate very, very much some help in this task.
