ggsave unused argument (filename = filename)

[zapster]

The following code fails with the current ggplot2 and tikzDevice versions.

library(ggplot2)
df <- data.frame(
  gp = factor(rep(letters[1:3], each = 10)),
  y = rnorm(30)
)
g <- ggplot(df, aes(gp, y)) + geom_point()

ggsave("plot.pdf", g, device=pdf) # OK 
ggsave("plot.tex", g, device=tikzDevice::tikz) # fail

I think the fix for tidyverse/ggplot2#2355 broke tikzDevice when used with ggsave. Here is the corresponding commit: tidyverse/ggplot2@a06e904

I don't know whether my issue relates to tikzDevice as well, but I'm getting the same issue with ggsave unused argument (filename = filename) after updating to 3.0.0.

Thanks for the report @zapster!

Are you sure that ggsave("plot.pdf", g, device=pdf) works correctly? For me it throws the same error message, while ggsave("plot.pdf", g, device="pdf") or ggsave("plot.png", g, device=png) work correctly.

BTW, here some background for this issue:

tikzDevice/R/tikz.R

Lines 227 to 229 in 0086e88

	# Ok, this sucks. We copied the function signature of pdf() and got `file`
	# as an argument to our function. We should have copied png() and used
	# `filename`.

Most likely we will update tikz() to accept both file and filename.

Hello @zapster,
latest version 0.12.1 fixes this. You can install it by devtools::install_github("daqana/tikzDevice"). Thanks for reporting this issue!

Alternative installation method if you already have the dependencies installed:

install.packages("tikzDevice", repo = 'http://www.daqana.org/drat')

General method:

if (!requireNamespace("drat", quietly = TRUE))
  install.packages("drat")
drat::addRepo("daqana")
install.packages("tikzDevice")

Thanks for fixing!
