I'm trying to clip a catalog using lidR (v2.0.1) package. I've tried with `lasclipCircle` and `lasclip`. It gives me the error: no point in ROI, but when I'm viewing the shapefile using `mapview` (I've exported the X and Y coordinates from this shapefile) and the catalog, they are at the same place. Here's my code. page1 <- catalog("O:/LiDAR/NB_LiDAR_16/page1") Buffer_16 <- readOGR(dsn = "O:/2018_Regen/Derived GIS", layer = "Buffer_16") X_16 <- Buffer_16@data[["DDLONG"]] Y_16 <- Buffer_16@data[["DDLAT"]] page1_points <- lasclipCircle(page1, xcenter = X_16,ycenter = Y_16, radius = 10) or page1_points <- lasclip(page1, Buffer_16) I get the following error: > Error : No point found for within region of interest 2. I got the same message for ROI 1 and all the other ROI as well.
