Hello All: Using the below dataset how can I make a barplot with Date(X) and NumEggs(Y) by Site. Then plot Temp(lineplot) It seems really simple, but I am having a hard time trying to do it by Site. Thanks
Hi Felipe, This might do what you want:
fdc<-read.table("fdc.dat",header=TRUE) fdc$Date<-as.Date(fdc$Date,format="%Y-%m-%d") library(plotrix) par(mar=c(5,4,4,4)) barp(fdc$NumEggs,names.arg=fdc$Date,xlab="Date",ylab="Number of eggs", main="Number of eggs by date",col=fdc$Site) # a low trick to align the x-axis for the temperature line startDate<-as.Date("2008-04-21",format="%Y-%m-%d") lines(fdc$Date-startDate,fdc$Temp/5) axis(4,at=10:12,labels=c(50,55,60)) mtext("Temperature",side=4,at=5,line=1) legend(2,14,levels(fdc$Site),fill=1:3) Jim ______________________________________________ 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.
