Error in saveGIF in R

[yanswiss]

Hey yihui, I have problems in plot animations in R, so I try your code as following,

• install.packages('devtools')
• library(devtools)
• install_github("yihui/animation")
• library(animation)
• saveGIF({for (i in 1:10) plot(runif(10), ylim = 0:1)})

however, I still got errors.

1: running command 'C:\Windows\system32\cmd.exe /c "C:\Program Files\ImageMagick-7.0.6-Q16\convert.exe" --version' had status 1 2: running command 'C:\Windows\system32\cmd.exe /c convert --version' had status 4 3: In normalizePath(path.expand(path), winslash, mustWork) : path[1]="C:\Program Files\ImageMagick-7.0.6-Q16/convert.exe": The system cannot find the file specified 4: running command 'C:\Windows\system32\cmd.exe /c "C:\Program Files\ImageMagick-7.0.6-Q16\convert.exe -loop 0 -delay 100 Rplot1.png Rplot2.png Rplot3.png Rplot4.png Rplot5.png Rplot6.png Rplot7.png Rplot8.png Rplot9.png Rplot10.png "animation.gif""' had status 1 5: In cmd.fun(convert) : '"C:\Program Files\ImageMagick-7.0.6-Q16\convert.exe -loop 0 -delay 100 Rplot1.png Rplot2.png Rplot3.png Rplot4.png Rplot5.png Rplot6.png Rplot7.png Rplot8.png Rplot9.png Rplot10.png "animation.gif""' execution failed with error code 1 6: running command '"C:\Program Files\ImageMagick-7.0.6-Q16\convert.exe -loop 0 -delay 100 Rplot1.png Rplot2.png Rplot3.png Rplot4.png Rplot5.png Rplot6.png Rplot7.png Rplot8.png Rplot9.png Rplot10.png "animation.gif""' had status 127

[yanswiss]

the code is exactly the example you gave: saveGIF({for (i in 1:10) plot(runif(10), ylim = 0:1)})

i just got a plot with 10 still points.

I have no idea, view your picture in any browser (Chrome ,Firefox, Edge), animation still doesn't play? Sometimes, GIF pictures doesn't animate in windows picture viewer.

If it still doesn't work, remove it and generate a new gif picture again, upload the picture on Github.

okay, now it works in Firefox. you are right, not IE. is it supposed still also with imagemagick displayer?

[yulijia]

Maybe, I am not quite sure.
