Like the latter it passes on its theories but it also passes on a critical attitude towards them. The theories are passed on not as dogmas but rather with the challenge to discuss them and improve upon them. -Karl Popper ...consider yourself a guest in the home of other creatures as significant as yourself. -Wayside at Wilderness Threshold in McKittrick Canyon, Guadalupe Mountains National Park, TX Cumberland Piedmont Network Forest Pest Monitoring Website http://science.nature.nps.gov/im/units/cupn/monitor/forestpest/forest_pests.cfm Cumberland Piedmont Network Cave Cricket Monitoring Website: http://science.nature.nps.gov/im/units/cupn/monitor/cavecrickets/cavecrickets.cfm ______________________________________________ R-help@r-project.org 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.
