I'm trying to change a qplot to a ggplot. The reason is because I want two plots of the same data. One a bar char, the other a line graph. What I'm trying:
#MSU_graph_m1b <- qplot(Int_Start,LicPrLsys4HMSU,data=cpprdald2_m1,geom="bar",stat="identity",color=System_alias); MSU_graph_m1 <- qqplot(cpprdald2_m1,aes(x=Int_Start,y=LicPrLsys4HSMU,colour=System_alias)); MSU_graph_m1b <- MSU_graph_m1+geom_bar(); #MSU_graph_m1l <- qplot(Int_Start,LicPrLsys4HMSU,data=cpprdald2_m1,geom="line"); MSU_graph_m1l <- MSU_graph_m1+geom_line(); The commented lines are what works. What fails is the first ggplit() like: > MSU_graph_m1 <- > qqplot(cpprdald2_m1,aes(x=Int_Start,y=LicPrLsys4HSMU,colour=System_alias)); Error in as.matrix.data.frame(x) : dims [product 9912] do not match the length of object [9923] > cpprdald2_m1 is: > str(cpprdald2_m1) 'data.frame': 168 obs. of 60 variables: and Int_Start and LicPrLsys4HSMU are variables in cpprdald2_m1. Int_Start is a POSIXlt. LicPrLsys4HSMU is a number. I have also tried with x=as.character(Int_Start) in the aes(). I am using the book "R GRAPHICS COOKBOOK" as my source of examples. I am obviously oblivious to something. -- There is nothing more pleasant than traveling and meeting new people!
