Subject: [R] Help me please: gplot, facets_wrap and ordering of x axis
dates
I have a text file of data as below and doing a ggplot line plot of all
the ids as separate mini line plots which works with the following code.
Problem how do I order the dates for each id plot on the x axis so that
the dates are going from oldest to most recent????
Thanks in advance
Dave
CODE:
a<-read.table("DATA",header=TRUE);
b<-a[order(as.Date(a$date, format="%m/%d/%Y")),]
ggplot(data=b) + geom_line(aes(x=date, y=value, group=id, colour=
factor(id))) + facet_wrap(~id, scales = "free")
DATA:
id????? date??? value
