I am trying to manually knit an rmd document which calls a figure fig1.gif.

! Unable to load picture or PDF file 'fig1.gif'.
<to be read again> 
               }
l.91 \includegraphics{fig1.gif}

The way I call the figure is:

![](fig1.gif)

The figure DOES exist in the directory. Any idea what the problem might be?

    `pdflatex` and `xelatex` do not accept `gif` pictures - see https://tex.stackexchange.com/questions/7602/how-to-add-a-gif-file-to-my-latex-file. The easiest way is probably to convert the gif to png. – Stéphane Laurent Aug 30 '18 at 11:40

I don't have your code, but i can give you 2 hints:

  1. Make sure that your file is next to your markdown file in the same directory.
  2. Try relative pathof the file.
  3. Write a short snippet which checks if R can find your file.

I found a sample from this question. 

        imgAddress="./ADDRESS bla bla/fig1.gif"     
         if (!file.exists(imgAddress)) {
            print("File is not found") }
         }

I should cast doubt on the way which you load the image. There are several packages which ,may help you:

library(magick)
tiger <- image_read_svg('http://jeroen.github.io/images/tiger.svg', width = 400)
print(tiger)

OR

earth <- image_read("https://jeroen.github.io/images/earth.gif") %>%
  image_scale("200x") %>%
  image_quantize(128)

length(earth)

Please read the below link. it will be usefull.

  • I think the problem might be something else. It could be that the .gif is not a proper format, becuase when I run the same code with a .png it runs properly. – Omry Atia Aug 30 '18 at 11:29
  • But, how does `![]` work? can you please explain it? – Sal-laS Aug 30 '18 at 11:30
  • --- dev='cairo_pdf' date: Sys.Date output: pdf_document: fig_caption: no latex_engine: xelatex urlcolor: blue --- ```{r global_options, include=FALSE, dev='cairo_pdf' } knitr::opts_chunk$set(fig.pos = 'h') ``` ```{r, echo=FALSE} ``` ```{r setup, include=FALSE, dev='cairo_pdf' } ``` ![](fig1.jpg) If you run this, you will get a pdf with the figure – Omry Atia Aug 30 '18 at 11:33

    Sure! Thanks for the effort. In the end it was the format of the figure that caused the bug... – Omry Atia Aug 30 '18 at 11:41
  • I would generally recommend that you include graphics using the `includes_graphics` command: https://stackoverflow.com/a/49856416/7347699 – Michael Harper Sep 02 '18 at 07:14
