Just started learning ggplot and I'm trying to change my groups to show different geom lines (i.e. one dashed, one smooth/straight line). Below is a mock of my code and how my plot currently looks:
ggplot(longdat,aes(visitnum,score, colour=Groups)) +
stat_summary(fun.y="mean", geom="line", size=.25 ) + stat_summary(fun.y="mean", geom="point") +
scale_x_continuous(name="Timepoints",breaks=c(0,4,12),labels=c("Time 1","Time 4","Time 12")) +
scale_y_continuous(name="Levels") +
theme(axis.text.x=element_text(angle=45,hjust=1))
I want to change the plot to black and white. However before I do that, I would need to change the lines so I can clearly see the difference between the 2 groups in b&w.
Below is my current code but it seems to re-connect the timepoints in a weird way:
ggplot(longdat,aes(visitnum,score, group=Groups)) +
geom_line(aes(linetype=Groups)) +
geom_point() +
stat_summary(fun.y="mean", size=.25 ) + stat_summary(fun.y="mean") +
scale_x_continuous(name="Timepoints",breaks=c(0,4,12),labels=c("Time 1","Time 4","Time 12")) +
scale_y_continuous(name="Levels") +
theme(axis.text.x=element_text(angle=45,hjust=1))
I've managed to change the group line types (albeit still not as obvious b/w the two groups), but now its connecting the mean scores between the 3 timepoints in a weird way...
Not sure what's causing this, or whether I have to implement the "geom_line" and "geom_point" functions within my "stat_summary" functions?
Any assistance would be appreciated.
