Hi, I need to produce a standard report for several variables in Sweave and thus would need the possibility to define a TeX-command which includes R-code like \newcommand{\meansd}[1]{The mean is \Sexpr{mean(#1)} and the standard deviation is \Sexpr{sd(#1)} . } and then just write \meansd{age} in the latex code to get the whole sentence. The above does not work, since Sweave ignores the \newcommand and does not expand the \statistics Is there an...

bonjour, i'm a mathematic teacher and i have a question for R-developers : is it possible to have (in the future) a boxplot with whiskers from the first decile to the ninth decile, as usual in secondary french schools... by example : boxplot(serie,range=-1) for french boxplot ? cordialement, jean-pierre lyc?e jean zay orl?ans, france http://mathazay.free.fr/spip/

Dear R-Devel List, **TL;DR:** The function **parLapplyLB** of the parallel package has [reportedly][1] (see also attached RRD output) not been doing its job, i.e. not actually balancing the load. My colleague Dirk Sarpe and I found the cause of the problem and we also have a patch to fix it (attached). A similar fix has also been provided [here][2]. [1]:
