"the argument has already been evaluated" error

[codyschulz]

When I attempt to run the CRAN example on my machine (scatterpie 0.1.0, Windows 10, R 3.4.4, ggplot2 2.2.1), I receive the following error: "Error in (function (x, strict = TRUE) : the argument has already been evaluated"

Any ideas about what might be going on?

Just noticed that scatterpie is compatible with the dev version of ggplot2. Will try that. Sorry.

Turns out that with the development version of ggplot2, when the following code is run:

library(ggplot2)
d <- data.frame(x=rnorm(5), y=rnorm(5))
d$A <- abs(rnorm(5, sd=1))
d$B <- abs(rnorm(5, sd=2))
d$C <- abs(rnorm(5, sd=3))
ggplot() + geom_scatterpie(aes(x=x, y=y), data=d, cols=c("A", "B", "C")) + coord_fixed()

the following error is thrown:

Error in `[.data.frame`(data, , xvar) : undefined columns selected

Edit: The code works when I use ggplot2 2.2.1 and the scatterpie December 2017 commit.

How do you get the December 2017 commit? I also get that error.

it works with latest versions.

I get the same error message still, using the latest R version 3.6 and the dev version of ggplot. I think the error must be somewhere within the geom_scatterpie() function, and how it plots the aesthetics? This is the head of my data set, A,B,C are the proportion that I would want to display in a pie chart. x and y are coordinates, first row is the site ID.

site x y A B C 1 613496 267409 0.75 0.25 0.00 2 609445 225330 0.50 0.25 0.25 3 605997 220876 0.50 0.25 0.25 4 607744 250786 0.50 0.25 0.25 5 662647 195819 0.50 0.25 0.25 6 664315 212930 0.50 0.25 0.25

This is the error message:

Error in [.data.frame(data, , xvar) : undefined columns selected

Thank you so much for your help!

It seems to work fine for you, it doesn't for me. Still get the error message, even when I copy your exact code. It might be an issue with a package being masked. I'll try to figure it out and let you know. Thanks for your effort though!
