Hello.<br><br>I am running grass & R and want to overlay maps and graphs created using vector attributes stored in a MySQL database.<br><br>This is the essential script I am working with<br><br>...<br>province<-readVECT6("M_Province",
remove.duplicates=FALSE,ignore.stderr=TRUE)<br>sites<-readVECT6("M_Province",type="centroid",remove.duplicates=FALSE,ignore.stderr=TRUE)<br><br>par(fig=c(0, 1, 0, 1))<br>plot(c(0,10), c(0,10), type="n", xlab="v", ylab="c",axes=T )
<br>box()<br><br>par(new=T)<br>plot(province)<br><br>par(new=T,oma=c(0, 2, 0.5, 1.5))<br>plot(sites)<br><br><br>After execution the sites vector is wrongly displayed, meaning that centroids are sligthly translated from the original position.
<br>Neverthless they are right when using points(sites) instead of plot(sites).<br><br>Am I missing something?<br>
