Error in file.info(x, extra_cols = FALSE) : file name conversion problem -- name too long?

[mjdzr]

Hi

First of all, thank you for creating this package, it's amazing. I am working on some confidential data and use SlickR to create some plot carousel. Many datasets end up okay, but a few of them return the following error after I run the slickR function:

Error in file.info(x, extra_cols = FALSE) : 
  file name conversion problem -- name too long?

Unfortunately I cannot share the dataset, but I can confirm that the final_plot object, if called on its own, works and plots the desired output. But the slickR throws an error.

The code that I'm using:

for (i in 1){ #Create a one-slide carousel
  fig_list[[i]] <- 
    {
      svglite::xmlSVG(
        code = {

          g = ggplot(plotdata) +
            geom_point(aes(x = DATE2, y = VARIABLE_VALUE, shape = Censored, 
                           fill = TYPE, color = TYPE), color = "black"
                       , size = 3, alpha = 0.8) +         
            scale_x_date(date_breaks = "5 years", date_labels = "%b-%y") +
            theme_bw() +
            scale_shape_manual(values = c("TRUE" = 24, 'FALSE' = 21))

          #First plot, with legends
          p1 <- (
            g + 
              guides(fill = guide_legend(override.aes = list(shape = 21))) +
              theme(legend.position = "right",
                    axis.title.x=element_blank(),
                    axis.text.x = element_blank())
          )

          #Second plot: log, without legend
          p2 <- (
            g + scale_y_log10(labels = label_comma()) + 
              theme(legend.position = "none")
          )

          final_plot = ggdraw() +
            draw_plot( plot = p2, x = 0, y = 0, width = 1, height = .35 ) +
           #testing a table to be added on top of plots
            draw_plot( plot = tableGrob(iris[1, ], rows = NULL), x = 0, y = .7, width = 1, height = .3 ) +  
            draw_plot( plot = p1, x = 0, y = 0.35, width = 1, height = .35 ) 
          show(final_plot)
        },
        standalone = TRUE, width = 7)
    }
}

slickR(fig_list)

Error in file.info(x, extra_cols = FALSE) : 
  file name conversion problem -- name too long?

Note: if I remove scale_shape_manual(values = c("TRUE" = 24, 'FALSE' = 21)) the error diappears and slickR works well. Also if I don't add the table (tableGrob(iris[1, ], rows = NULL)), the slickR function works well.

Any ideas on why that error is thrown? I have also checked long/short path names for my project. There is no non-English character in the directory.

Thank you!
