My code that I've used is: mcgc <- ggplot(sam, aes(x = person,y = m, colour = X)) + geom_point(size = 0.75) + scale_colour_gradient2(high="red", mid="green", limits=c(0,1), guide = "colourbar") + geom_hline(aes(yintercept = mad, linetype = "mad"), colour = "blue", size=0.75, show_guide = TRUE) + geom_hline(aes(yintercept = mmad, linetype = "mmad"), colour = "black", size=0.75, show_guide = TRUE) + facet_wrap(~ Plan, scales = "free", ncol = 4) + scale_linetype_manual(name = "Plan of Health Care", values = c("mad" = 1, "mmad" = 1),guide = "legend")
For this data: Data: Plan Person X m mad mmad 1 1 95 0.323000 0.400303 0.12 1 2 275 0.341818 0.400303 0.12 1 3 2 0.618000 0.400303 0.12 1 4 75 0.320000 0.400303 0.12 1 5 13 0.399000 0.400303 0.12 1 6 20 0.400000 0.400303 0.12 2 7 219 0.393000 0.353350 0.45 2 8 50 0.060000 0.353350 0.45 2 9 213 0.390000 0.353350 0.45 2 15 204 0.496100 0.353350 0.45 2 19 19 0.393000 0.353350 0.45 2 24 201 0.388000 0.353350 0.45 3 30 219 0.567 0.1254 0.89 3 14 50 0.679 0.1254 0.89 3 55 213 0.1234 0.1254 0.89 3 18 204 0.6135 0.1254 0.89 3 59 19 0.39356 0.1254 0.89 3 101 201 0.300 0.1254 0.89 I'm trying to manipulate the x axis using the following, only because the data can get very large and there is just way too many Persons to fit on the x-axis and I need to reduce it so its legible: scale_x_continuous(breaks = c(min(person), median(person), max(person)), labels = c(min(person), median(person), max(person))) However, given that I had to change `person` into a factor to order the data properly, the above code does not work. I get the errors, depending on how I fiddle around with the code: Error: Discrete value supplied to continuous scale Error in Summary.factor(c(1L, 2L, 3L, 4L, 5L, 6L, 7L, 8L, 9L, 10L, 11L, : min not meaningful for factors Changing `person` to numeric does not work, as the accumulated `person` for the entire dataset will then be on each Plan figure panel, as opposed to the scale specific for each Plan. That is, the x-axis for each panel (Plan) should have a scale beginning from its lowest Person to its highest Person (ie Plan 1 should have an x-axis that goes from 1 to 6 but Plan 3 has one that goes from 14 to 101). Changing the Person to numeric, the x-axis for all panels starts at 1 and goes to 101. Is there a work around for this? ______________________________________________ R-help@r-project.org mailing list 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.
