Error using Animation package R

Question

Tried to run the following code in R:

ani.options(
   convert = shQuote("C:/Program Files/ImageMagick-6.9.0-Q16/convert.exe")
)
 saveGIF(
{
  for (i in 1:10) plot(runif(10), ylim = 0:1)
},
 movie.name = "test.gif", 
interval = 0.2, 
ani.width = 300, 
ani.height = 300,
outdir = getwd()
)

Getting the error message:

Executing: 
"\"C:/Program Files/ImageMagick-6.9.0-Q16/convert.exe\"" -loop 0 -delay 20     Rplot1.png Rplot2.png Rplot3.png

The filename, directory name, or volume label syntax is incorrect.

Could someone please point on my mistake.

Answer 1

I had the same issue, and it seems it is due to the path to convert. If I type:

ani.options(convert = shQuote('C:/Program Files/ImageMagick-6.8.7-Q16/convert.exe'))

And then check the path

ani.options("convert") [1] "\"C:/Program Files/ImageMagick-6.8.7-Q16/convert.exe\""

However, if I do:

ani.options(convert = 'C:/Program Files/ImageMagick-6.8.7-Q16/convert.exe') ani.options("convert") [1] "C:/Program Files/ImageMagick-6.8.7-Q16/convert.exe"

It is the correct path and saveGIF works.... weird things...
