• Evolution #4103 : Autoriser /local/cache-gd2/ et /local/cache-vignette/ dans robots.txt

  28 mai 2018, par b b

  Hop,

  Dans mon cas, à partir du moment où une image est visible sur une page, je considère qu’elle doit être indexée car c’est du contenu et un point d’entrée au même titre que le texte (recherche par image).

  C’est plus fin que ça, autoriser l’indexation de local/ ferait que toutes les tailles de vignettes d’une images seraient indexées par les moteurs alors que l’image originale l’est déjà (ce qui suffit amplement). De plus, cela pourrait générer pas mal de trafic en plus sur les sites uniquement pour indexer des images "non utiles aux visiteurs", bref ça ne serait pas super écolo :p

• 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.
