ggally

Here's the minimal case: df <- data.frame(x=1:5, y=1, col=1:5) mapping <- aes(x=x, y=y) ggplot(df, mapping) + geom_point(size=10) Now I want to add (or overwrite) another aesthetic (colour) to the existing mapping object. The desired plot is ggplot(df, aes(x=x, y=y, colour=col)) + geom_point(size=10) I'm sure there exists a convenience function for this, but it is not listed in the documentation, and browsing the source didn't help either. I once seem to have stumbled upon something like AddOrOverrideAes , but no idea where exactly. Here's what my current solution is: add_aes <- function

With library(GGally) data(diamonds, package="ggplot2") diamonds.samp <- diamonds[sample(1:dim(diamonds)[1],200),] # Custom Example ggpairs( diamonds.samp[,1:5], mapping = ggplot2::aes(color = cut), upper = list(continuous = wrap("density", alpha = 0.5), combo = "box"), lower = list(continuous = wrap("points", alpha = 0.3), combo = wrap("dot", alpha = 0.4)), diag = list(continuous = wrap("densityDiag")), title = "Diamonds" ) I get How do I make the diagonal density plots to not be filled, and only show the lines? Kind of works... but not really. This is really ugly - in terms of code - because

GGally::ggpairs plots nice graphs like following one. Only thing I seek to refine it even more is to remove all gridlines in upper part of plot, where is correlation coefficient. An maybe also draw rectangle around each upper graph. library("GGally") data(iris) ggpairs(iris[, 1:4], lower=list(continuous="smooth", params=c(colour="blue")), diag=list(continuous="bar", params=c(colour="blue")), upper=list(params=list(corSize=6)), axisLabels='show') tonytonov Check out this related question and my forked repo. Use assignInNamespace to modify ggally_cor function as shown in the aforementioned

I'd like to arrange my ggpairs plots with arrangeGrob : library(GGally) library(gridExtra) df <- structure(list(var1 = 1:5, var2 = 4:8, var3 = 6:10), .Names = c("var1", "var2", "var3"), row.names = c(NA, -5L), class = "data.frame") p1 <- ggpairs(df, 1:3) p2 <- ggpairs(df, 1:2) p <- arrangeGrob(p1, p2, ncol=2) which results in this error: Error in arrangeGrob(p1, p2, ncol = 2) : input must be grobs! Is there a way to work around this problem? tonytonov Unfortunately, I cannot see how that is possible. First, it's not going to work with gridExtra , since arrangeGrob operates on TableGrob objects

I am plotting a scatterplot matrix using ggpairs . I am using the following code: # Load required packages require(GGally) # Load datasets data(state) df <- data.frame(state.x77, State = state.name, Abbrev = state.abb, Region = state.region, Division = state.division ) # Create scatterplot matrix p <- ggpairs(df, # Columns to include in the matrix columns = c(3,5,6,7), # What to include above diagonal # list(continuous = "points") to mirror # "blank" to turn off upper = "blank", legends=T, # What to include below diagonal lower = list(continuous = "points"), # What to include in the diagonal

I saw these posts GGally::ggpairs plot without gridlines when plotting correlation coefficient use ggpairs to create this plot After reading I was able to implement this hack https://github.com/tonytonov/ggally/blob/master/R/gg-plots.r and my plot looks like this I think this is a good result but I cannot change the colors. A MWE is this library(ggally) # load the hack source("ggally_mod.R") # I saved https://github.com/tonytonov/ggally/blob/master/R/gg-plots.r as "ggally_mod.R" assignInNamespace("ggally_cor", ggally_cor, "GGally") ggpairs(swiss) Now I want to run ggpairs(swiss, lower=list

I have some code in a Shiny app that produces the first plot below. As you can see the font size varies with the size of the correlation coefficient. I would like to produce something similar with ggpairs (GGally) or ggplot2. The second image below was produced with the following code: library(GGally) ggpairs(df, upper = list(params = c(size = 10)), lower = list(continuous = "smooth", params = c(method = "loess", fill = "blue")) ) As you can see the size of the correlation font is adjustable using size but when I set a vector of sizes only the first value is used. I would also like to remove
