ggsave error with ggplot 3.3.5 when run using Rscript

[rzambre]

When running with Rscript, ggsave throws an error with ggplot 3.3.5. I do not see the error with ggplot 3.3.3.
Usage and example below.

R version 4.0.2

---

Example plotter.R (run with any csv file with any random data with a minimum of two columns):

library(tidyverse)

latency <- read.csv("latency.csv", header=TRUE)

plot_and_save <- function(df, xval, yval, title, subtitle, xlabel, file) {
  p <- ggplot(df, aes_string(x=xval, y=yval, group=1)) +
    geom_line(size = 0.5) +
    geom_point(size = 1.5, alpha = 1) +
    theme_minimal() +
    expand_limits(y=0) +
    xlab(xlabel) +
    ggtitle(title, subtitle = subtitle) +
    theme(
      axis.text.x = element_text(angle=90,hjust=1),
      axis.title.y = element_blank()
    )
  ggsave(filename=file, p, device=pdf, dpi=500)
}

plot_and_save(df=latency,
              xval="bytes",
              yval="lat_avg",
              title="Ping pong",
              subtitle="Latency (us)",
              xlabel="Message size (bytes)",
              file="latency.pdf"
)

Running and output:

Rscript ./plotter.R
Error in (function (file = if (onefile) "Rplots.pdf" else "Rplot%03d.pdf",  :
  unused argument (filename = "latency.pdf")
Calls: plot_and_save -> ggsave -> dev -> do.call
Execution halted

Thanks, this seems the same issue: #4539. But, in this case, maybe you can just remove device=pdf argument as it's automatically inferred from the file extension?

[rzambre]

Yes, removing device=pdf worked with 3.3.5

Thanks for confirming. Let me close this and track the problem on #4539.
