Dear R experts, I am newbie on the R use, now I want to sort my data by mean in a descending and not acending order (like I have done so far). If any of you could help me with this, it would be really appreciated! Thanks! Please find the script attached with the summary of the dat object pt<-summarySE(dat, measurevar="Time", groupvars=("Prey"))# pt Prey N Time sd se ci 1 cochinilla 10 351.6000 99.34103 31.41439 71.06429 2 hormiga 17 193.2353 92.50014 22.43458 47.55918 3 larva 18 259.0667 93.84009 22.11832 46.66558 4 termita 19 144.6316 65.30895 14.98290 31.47791 pt$Prey=c("Isopoda","Formicidae","Lepidoptera","Isoptera") bymean <- with(pt, reorder(Prey, Time, mean))# REordenar por promedio library(ggplot2) png(filename = "plotloxo1.png", width = 500, height = 500) e <- qplot(bymean, pt$Time,size=3)+theme(panel.grid.major = element_blank(), panel.grid.minor = element_blank(), panel.background = element_blank(), axis.line = element_line(colour = "black"))# e<-e+theme(legend.position="none")# e+ geom_errorbar(data = pt, aes(x = pt$Prey, y = pt$Time, ymin = pt$Time - pt$ci, ymax = pt$Time + pt$ci), colour = "black", width = 0.4, size=0.5)+ #Añadir barras de error xlab("Prey") + ylab("Time (Seconds)") + ggtitle("Total PM25 emissions") dev.off()# [[alternative HTML version deleted]] _______________________________________________ R-sig-ecology mailing list R-sig-ecology@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-ecology
