Dear R experts, Maybe my question is too basic and I apologize for that. I am having an issue currently by trying to change manually the symbols of the series. I need to put them manually, instead of using the symbols that R gives by default and produce a plot with the classic style. For example I need to put the symbols 16 and 2, but I have been unable to do it so far. Also, I need to remove the grey background from the seiries but I have been unable to do it too.
Any help you can provide will be really helpful. Below, I am providing the script as well as the picture I gio with it If necessary I added the dataset. Many thanks ################################################################################# it<-read.table("immotime.txt",header=TRUE) it str(it) names(it) fit3<-lm(Time ~ Sp*Ratio, data=it) anova(fit3) plot(fit3) summary(fit3) a$lPeso <- log(Peso) library(ggplot2) p <- ggplot(it,aes(x=Ratio,y=Time)) + geom_point(aes(shape=factor(Sp))) p=p + geom_smooth(aes(linetype=factor(Sp), ),colour="black", method='lm', se=F)+theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank(), panel.background = element_blank(), axis.line = element_line(colour = "black")) p ################################################################################# Plot: https://postimg.org/image/3vm2uleip/ dataset "it" http://textuploader.com/d593h [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
