[Qgis-user] Problem with SDA4PP/Linked Statistical Display

[Volkan Kepoglu]

updated with ver. 0.142, could you try that if it is fixed?

1. added loading of rJava package function
2. changed the style of loading of iplot package: first checks the package
installed or not
and then loads the package but skips to control the package whether it is
loaded or not,
because, most probably, i think that there is a bug for iplots package. even
it is loaded, sometimes do not return true.
for this reason, i prefered not to control the library whether loaded or
not.
