• Knitr Plot Animation - disappearing output files ?

  20 avril 2015, par tcs

  I downloaded the latest ffmpeg (exe version), unzipped the files, renamed the directory to ffmpeg, copied the directory into c :\Program Files. I appended my PATH variable to include c :\Program Files\ffmpeg\bin. Finally, I restarted Rstudio.

  While attempting to run the following code chunk :

  ```{r perf_plot, fig.width=7, fig.height=6, fig.show='animate'}
  
  library(corrplot)
  
  corrplot(m, method = "circle")
  
  m<-sequence_2_matrix(perf_list[[1]])
  
  corrplot(m)
  
  for (i in 2:length(perf_list)) {
  
    m<-(m*(i-1)+sequence_2_matrix(perf_list[[i]]))/i
  
    corrplot(m,method = "circle")
  
  
  
  }

  I see within the output in in my RMarkdown window that the ffmpeg call seems to be successfully run, but while watching the directory where my code is located the png that is attempted to be created can often disappear, or not appear at all. Strangeness.

  Any ideas on what might be happening ? I’ve tried adding in other graphs, and I see this random behavior of the file folder appearing disappearing, sometimes the file is created, other times not.

• Anomalie #2915 : dans privé en colonne gauche dans h3, chevauchement texte sur lien "plus d’info"

  4 mai 2015, par chan kalan

  Je viens de mettre une vue d’écran un peu plus tôt (https://core.spip.net/attachments/download/717/Capture%20d_%C3%A9cran%202015-05-03%20%C3%A0%2023.14.12.png) , au même endroit que toi en page accueil de l’espace privé (et mes exemples précédents se sont perdus depuis 2 ans... désolé), tu peux essayer avec un texte un peu différent, ou en reprenant le même que moi si tu veux, même si ça peut changer en fonction des typographies, je sais pas... Quoi qu’il en soit, l’image n’est pas flottante, elle est en positionnée en absolu, donc c’est bien normal que le texte se superpose.
