Hi You'll need to save them manually to avoid name conflicts -- save.image() is the function to do so but you need to give a file name. Or it is necessary have separate folder for each R session. Regards Petr Michael On Apr 10, 2012, at 7:41 AM, ya xinxi...@163.com wrote: Hi

Re: [R] Legend based on levels of a variable

Thanks, anyway, using build-in R features is preferable for colours with(data, plot(axis1, axis2, col= c(red, blue, green)[as.numeric(data$Region)])) legend(topright, legend=levels(data$Region), fill= c(red, blue, green)) although sometimes can be preferable to get advantage of grid graphic
