To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of. ~ Sir Ronald Aylmer Fisher The plural of anecdote is not data. ~ Roger Brinner The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data. ~ John Tukey -----Oorspronkelijk bericht----- Van: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] Namens John McKown Verzonden: woensdag 23 juli 2014 15:48 Aan: r-help Onderwerp: [R] Trying to change a qplot() to a ggplot()+ 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!
