I'm attempting to make a scatterplot with ggplot. My data set is made up for 4 columns, three of which are factor variables and the fourth is a continuous variable.
'data.frame': 108 obs. of 4 variables:
$ Name : Factor w/ 3 levels "Con","Tag","Vel": 1 2 3 1 2 3 1 2 3 1 ...
$ Model: Factor w/ 3 levels "1","2","3": 1 1 1 1 1 1 1 1 1 1 ...
$ IndexSeq : int 1 1 1 2 2 2 3 3 3 4 ...
$ Measurement : num 0.736 0.377 0.377 1.072 0.513 ...
plot5<-ggplot(plot.data.test, aes(IndexSeq, Measurement, color=Model)) + geom_jitter()+
geom_hline(aes(yintercept=Measurement, color=Model), supplot)+
facet_wrap(~plot.data.test$Name)
"Supplot" contains the means by "Name" and by "Model", so there are 9 data points. I read numerous posts that said to add in the horizontal mean on a panel graph you need to have separate data.frame that contains the aggregated measurements. When I follow all of that, I get the following error:
Error in `$<-.data.frame`(`*tmp*`, "PANEL", value = c(1L, 2L, 3L, 1L, : replacement has 108 rows, data has 9
What am I doing wrong?
Cheers!
