Knitr does not display googleVis

Question

I am having problems with Rsutdio and knitr on Windows 7 to render a simple gvisTable. Here is my code

```{r results='asis'} require(googleVis) op <- options(gvis.plot.tag="chart") data(iris) t = gvisTable(data = iris) print(t) ``` 

and here is my mistake:

pandoc.exe: Failed to get https://www.google.com/jsapi?callback=displayChartTableID14c4345d7f3 FailedConnectionException2 "www.google.com" 443 True connect: failed (Connection timeout (WSAETIMEDOUT)) Erreur: pandoc document conversion failed with error 61

My Rstudio version: 0.98.1091 And my SessionInfo:

 R version 3.1.2 (2014-10-31) Platform: x86_64-w64-mingw32/x64 (64-bit) locale: [1] LC_COLLATE=French_France.1252 LC_CTYPE=French_France.1252 LC_MONETARY=French_France.1252 [4] LC_NUMERIC=C LC_TIME=French_France.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] plotrix_3.5-10 data.table_1.9.4 googleVis_0.5.6 knitr_1.8 loaded via a namespace (and not attached): [1] chron_2.3-45 digest_0.6.4 evaluate_0.5.5 formatR_1.0 htmltools_0.2.6 plyr_1.8.1 Rcpp_0.11.3 [8] reshape2_1.4 RJSONIO_1.3-0 rmarkdown_0.3.11 stringr_0.6.2 tools_3.1.2 yaml_2.1.13 

or this code works fine:

 ```{r results='asis'} require(knitr) data(iris) kable(iris) ``` 

Do you have any idea about the problem with googleVis in this context? Thanks in advance for any help.

Answer 1

Pandoc is trying to load a googleVis diagram so that it can embed a static / offline copy in your document. You can work around the problem by telling Pandoc not to create a separate document (i.e. do not add resources to it, which causes the problem) - add this to the beginning of the document or just the text between --- if you already have a YAML header:

 --- output: html_document: self_contained: no --- 

Pandoc should not have problems retrieving resources over https. If you have time to reproduce the problem outside the rmarkdown workflow (i.e. On Vanilla Markdown → HTML conversion) and find that it is still a problem, please report the problem to Pandoc: https://github.com / jgm / pandoc / issues .
