Dear listers, After activating the name space for my bioconductor package (prada) I successfully ran R CMD check. However when loading the package in R and running the examples the imported function brewer.pal from package RColorBrewer is not found. I can directly call brewer.pal from the RColorBrewer name space typing RColorBrewer::brewer.pal, but it is not imported into my prada name space. When I attach RColorBrewer, the example runs fine.

If noone has produced one yet, does anyone have any idea when one will be available? Many Thanks Daniel Brewer

Hi, I'm trying to create a heatmap with color ranges for different values in my matrix. For example: If x > 5 , use orange gradient if x < 1.5, use red gradient ..... Right now I have the following: orgPal<-brewer.pal(3,"Oranges") bluPal<-brewer.pal(3,"Blues") redPal<-brewer.pal(3,"Reds") grad <- ifelse(randMat > 5,orgPal,ifelse(randMat<1.5,redPal,bluPal)) hmap <- heatmap(randMat,Rowv=NULL, Colv=NULL,dendrogram="none",col = grad, scale="column&q...

Heineken NV and Carlsberg A/S may be fined after the European Commission charged that they conspired to curb competition in the Dutch and Danish beer markets from 1993 to 1996. The European Union's antitrust regulator said evidence collected in raids two years ago showed the two brewers broke EU law by agreeing not to sell ``intensively'' in each other's territory. The companies denied the allegations. Competition Commissioner Mario Monti is cracking down on price fixing in industries from vitamins to papermaking. He took on Europe's beer industry last year with...
