[spatstat] problem with a psp Line Segment Pattern when plotting and pointsOnlines performing
Hi, I Have a problem with a psp object. I can't plot it, neither perform a pointsOnLines calculation on it. --- Here is what I obtain with my different operations:
track <- readOGR("voie.shp", "voie")
OGR data source with driver: ESRI Shapefile Source: "voie.shp", layer: "voie" with 1 features and 14 fields Feature type: wkbLineString with 2 dimensions
track.psp <- as(track, "psp")
Message d'avis : In as.psp.SpatialLinesDataFrame(from) : 13 columns of data frame discarded
plot(track.psp)
Erreur dans image.default(c(893999.767449278, 895777.422954333), c(Inf, -Inf : 'x' and 'y' values must be finite and non-missing #plot(track) is OK
pts <- pointsOnLines(track.psp, eps=50)
Erreur dans ppp(x = x, y = y, window = win) : all coordinate values are NA or NaN --- Any help would be appreciated. The related SpatialLinesDataFrame track object is attached to this mail if you'd like to have a look.. Thanks! -------------- next part -------------- An HTML attachment was scrubbed...
