I have read in Paul Murrell's book R Graphics about how to use a bitmap as background for a plot (page 107). Also, I routinely use function read.shape() in package maptools to read maps in shapefile format. Now, I would like to overlay an aerial photograph in .jpg format and a map. I think I could do the alignment manually for each case, but wonder if there is a better, automated way. I notice that the .jpg file has a companion .jgw file which may be of help.
If someone has written code for such kind of alignments or can direct me to detailed instructions on how to go about, I would be grateful. ft. -- Fernando TUSELL e-mail: Departamento de Econometría y Estadística [EMAIL PROTECTED] Facultad de CC.EE. y Empresariales Universidad del País Vasco Tel: (+34)94.601.3733 Avenida Lendakari Aguirre, 83 Secr: (+34)94.601.3740 E-48015 BILBAO (Spain) Fax: (+34)94.601.3754 ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
