As part of an effort to remove a specific geom from a plot I've already created (SO link here), I'd like to dynamically determine the geom type of each layer of a ggplot2 object. Assuming I don't ...

I'm trying to use ggplot2 / geom_boxplot to produce a boxplot where the whiskers are defined as the 5 and 95th percentile instead of 0.25 - 1.5 IQR / 0.75 + IQR and outliers from those new whiskers...

Is there some way to use a specific small image as a point in a scatterplot with ggplot2. Ideally I will want to resize the images based on an variable. Here's an example: library(ggplot2) p <...

I would like to implement diagnostics for Cox proportional hazards model with ggplot2, by creating new stats functions and ggproto objects. The idea is to benefit from grouping (by color, facet_gri...

I am trying to create a new geom that will create a wind radii chart from hurricane data. The data needed to run this came be generated from the following: storm_observation <- data_frame(long...

I'm using ggmap, and got the error below: Error: GeomRasterAnn was built with an incompatible version of ggproto. Please reinstall the package that provides this extension. I've installed the la...

Is it possible to display custom image (say png format) as geom_point in R ggplot? library(png) pic1 <- readPNG("pic1.png") png("Heatmap.png", units="px", width=3200, height=3200, res=3...

When I run the code from the accepted answer (Plot coordinates on map), I get the following error message on the first run after installing ggmap: # loading the required packages library(ggplot2)...

I've found the dplyr %>% operator helpful with simple ggplot2 transformations (without resorting to ggproto, which is required for ggplot2 extensions), e.g. library(ggplot2) library(scales) lib...

I am having a little trouble with my radar chart in R. Even though the plot is fine I am getting the following warning: > source('~/.active-rstudio-document') Warning message: In `levels<-`(...

I've been working on a radar plot recently and found a great bit of code on from Erwan Le Pennec. I've made a few edits, however there are some parts I couldn't work out how to remove the outermost...

This is actually two questions in one (not sure if goes against SO rules, but anyway). First question is how can I force a geom_text to fit within a geom_bar? (dynamically according to the values ...

I've been reading the vignette on extending ggplot2, but I'm a bit stuck on how I can make a single geom that can add multiple geometries to the plot. Multiple geometries already exist in ggplot2 g...

I know that in ggplot2 one can add the convex hull to a scatterplot by group as in library(ggplot2) library(plyr) data(iris) df<-iris find_hull <- function(df) df[chull(df$Sepal.Length, df$S...

I'm often using boxplots in my work and like ggplot2 aesthetics. But standard geom_boxplot lacks two things important for me: ends of whiskers and median labels. Thanks to information from here I'v...

I am following up a discussion started at: How can I make geom_area() leave a gap for missing values?. It seems like geom_ribbon is not longer leaving gaps for missing values. Please try to execute...

I try to use the new functionality of ggplot2 in R that allows creating our own stat_ functions. I'm creating a simple one to compute and plot an interpolated surface between points arranged on a 2...

I have been stuck with this for hours. When I run this : library(ggmap) set.seed(1) n=100 df <- data.frame(x=rnorm(n, 0, 1), y=rnorm(n, 0, 1)) TestData <- ggplot (data = df) + stat_densit...
