rstan plot error with ggplot2 2.2.0

[jasonqiangguo]

Summary:

traceplot(stan.fit, pars='theta', ask=TRUE)
Warning: Ignoring unknown parameters: ask
Error in [.unit(padding, 4) : index out of bounds ('unit' subsetting)

Description:

My ggplot2 version is the development version of ggplot2 (2.2.0) and when I want to briefly check the convergence using traceplot. But it gave me an error as above. Any solution?

RStan Version:

package ‘rstan’ was built under R version 3.2.5

R Version:

R version 3.2.4

Operating System:

Your operating system (e.g., OS X 10.11.6)

Hi Jason, The latest ggplot2 isn't fully compatible with the current rstan release. We will fix that (it might already be working on the develop branch of rstan), but in the meantime you can use our new bayesplot package (now on CRAN). If you have bayesplot loaded you can do: draws <- as.array(stan.fit, pars="theta") mcmc_trace(draws)

Hi!

I am using a similar technique as rstan does in another package and had the same trouble with ggplot2 2.2.0, To me it looks as if the problem is in ggplot2, but can be easily fixed from the rstan side. When you define the theme object, you do right now something like

.rstanvis_defaults <- new.env(parent = emptyenv())
.rstanvis_defaults$theme <- theme_bw(... some options...)

Changeing this to

.rstanvis_defaults <- new.env(parent = emptyenv())
.rstanvis_defaults$theme <- theme_bw(...some options..., base_size = 11, base_family = "Arial")

makes it work again - at least for me, So you have to explicitly specify the base_size and base_family option, the default does trigger the stupid mistake.

Hope that helps.

Thanks for the tip!

Thank you so much for the tip!

I seem to have the same problem six years later.

fit = stan_glm(Sepal.Width ~ Sepal.Length, data = iris)

fit
> stan_glm
> family:       gaussian [identity]
> formula:      Sepal.Width ~ Sepal.Length
> ...
# yes it fit

plot(fit)

> 3: Ignoring unknown parameters: linewidth 

R version 4.2.2 (2022-10-31)

bayesplot_1.10.0
rstanarm_2.21.3

EDIT: resolved with ggplot2_3.4.0
