Hi Ive got stuck using the code below to try to plot trajectories - columns are data recorded at time points, rows are cases. Ive used melt to turn the data long allowing me to group by time point and then plot using geom_point but I now need to join the points based upon the correct case (i.e. the first row in the original dataset). geo_segment allows me to specify start-end but I need to do this over multiple time periods....
Any help much appreciated thanks mike library(reshape2) library(ggplot2) library(ggthemes) library(cowplot) #Read raw data df = read.table("http://www.lecturematerials.co.uk/data/sample.csv", header=TRUE, sep=",", dec=".", na.strings=c("NA")) names(df)<-c("1","2","3","4") #Turn data from wide to long ds<-melt(df) ggplot(ds, aes(x = variable, y = value)) + geom_point (shape=19, size=5, fill="black") --- Mike Smith ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
