Since the upgrade of R (2.15.1>3.0.0) I get an error when using knitr on file.Rhtml and also with Lyx. The version of knitr is 1.1.
The error message is :
Erreur dans sum(figs) : 'type' (list) de l'argument incorrect
Calls: knit ... <Anonymous> -> process_group.block -> call_block -> block_exec
Any idea to solve this?

Update: knitr 1.2 is on CRAN now, in which this problem was fixed.
I think I have fixed this problem in the development version, which will be on CRAN soon. For now, please try
install.packages('knitr', repos = 'http://www.rforge.net/', type = 'source')
