[R] ggplot2 question: keeping the order as in the input data
Hello! I am using ggplot2 (see the code below) to plot the data in 'myplotdata'. The first column of 'myplotdata' is called "att.levels" and contains strings; the second column is called "WTP" and contains numeric values. Notice - I use 'coord.flip()' The command aes(x=att_levels, y=WTP), if I understand correctly, sorts things alphabetically based on the column 'att_levels'. Question 1: How can I reverse the order for x in the plot (also alphabetically but in the opposite direction)? Question 2: How can I just have exactly the same order as in the object 'myplotdata'? Thanks a lot! ggplot(myplotdata, aes(x=att_levels, y=WTP)) + geom_bar(stat="identity",fill="dark orange",colour="black", alpha = 1,position = "identity") + geom_text(aes(label=WTP),colour="black",size=4,hjust=1.1,position='dodge') + coord_flip() + xlab("") + ylab("") -- Dimitri Liakhovitski [[alternative HTML version deleted]]

[R] ggplot2 question: keeping the order as in the input data
Try making att_levels (or att.levels, whatever you really call it) into a factor with the levels in the order you like. E.g., aes(x = factor(att_levels, levels=unique(att_levels)), y = WTP) instead of aes(x = att_levels, y = WTP) Bill Dunlap Spotfire, TIBCO Software wdunlap tibco.com> -----Original Message----- > From: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org] On Behalf > Of Dimitri Liakhovitski > Sent: Wednesday, October 30, 2013 7:35 AM > To: r-help > Subject: [R] ggplot2 question: keeping the order as in the input data > > Hello! > > I am using ggplot2 (see the code below) to plot the data in 'myplotdata'. > The first column of 'myplotdata' is called "att.levels" and contains > strings; the second column is called "WTP" and contains numeric values. > Notice - I use 'coord.flip()' > > The command aes(x=att_levels, y=WTP), if I understand correctly, sorts > things alphabetically based on the column 'att_levels'. > Question 1: How can I reverse the order for x in the plot (also > alphabetically but in the opposite direction)? > Question 2: How can I just have exactly the same order as in the object > 'myplotdata'? > > Thanks a lot! > > ggplot(myplotdata, aes(x=att_levels, y=WTP)) + > geom_bar(stat="identity",fill="dark orange",colour="black", > alpha = 1,position = "identity") + > > geom_text(aes(label=WTP),colour="black",size=4,hjust=1.1,position='dodge') + > coord_flip() + > xlab("") + > ylab("") > > > > > -- > Dimitri Liakhovitski > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at r-project.org mailing list > stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
