geom-text

I'm making some graphs in ggplot and cannot figure out how to plot in graph text without specifying x and y positions. Lets say I'm making a graph like this. sp <- ggplot(mpg, aes(hwy, cty, label = "sometext"))+ geom_point() I want to add the label to be printed in the same way in every graph. Calling the following simply prints text at every x, y value supplied to aes . sp + geom_text() I could manipulate the x y data supplied to geom_text() to ensure that the text remained in the same relative position between graphs but is there not a simply way to call position by default positions like

I would like to have labels on only the top part of my stacked bar plot. Here is my data frame: #create data frame building <- c("Burj \nKhalifa", "Zifeng \nTower", "Bank of \nAmerica Tower", "Burj Al Arab", "Emirates \nTower One", "New York \nTimes Tower", "Emirates \nTower Two", "Rose Rayhaan \nby Rotana", "The \nPinnacle", "Minsheng \nBank Building") occupiable<- c(585, 317, 235, 198, 241, 220, 213, 237, 265, 237) nonoccupiable <- c(244, 133, 131, 124, 113, 99, 97, 96, 95, 94) df.build <- data.frame(building, occupiable, nonoccupiable) #melt data frame for stack bar plot df.build2 <- melt

The short version : How would I make this contrived code plot a proper greek beta character AND the rest of the label string, with the space and the less than character and the numbers formatted as typed? library("ggplot2") df<-data.frame(a=1:15,b=6:20) ggplot(data=df, aes(x=a,y=b)) + geom_point() + geom_text(x=5,y=4,label="beta=1.00 p<0.0001", parse=TRUE) If I leave out the ", parse=TRUE" argument, the string works great, but won't give me a real greek beta. If I leave it in, all hell breaks loose. The long version (and why I can't find a duplicate): I finally discovered in How to use Greek

This question already has an answer here: Showing data values on stacked bar chart in ggplot2 2 answers I would like to position the corresponding value labels in a geom_col stacked barchart in the middle of each bar segment . However, my naive attempt fails. library(ggplot2) # Version: ggplot2 2.2 dta <- data.frame(group = c("A","A","A", "B","B","B"), sector = c("x","y","z", "x","y","z"), value = c(10,20,70, 30,20,50)) ggplot(data = dta) + geom_col(aes(x = group, y = value, fill = sector)) + geom_text(position="stack", aes(x = group, y = value, label = value)) Obviously, setting y=value/2 for
