[R] graph: horizontal bar reflecting number of data

[Jim Lemon]

Hi Tagmarie,
This might help:

datframe$numberdata<-as.numeric(as.character(datframe$numberdat))
library(plotrix)
barcol<-color.scale(datframe$numberdat,extremes=c("black","white"))
barplot(matrix(datframe$numberdat,nrow=2,byrow=TRUE),
 beside=TRUE, horiz=TRUE,names.arg=paste("Week",1:3),
 col=matrix(barcol,nrow=2,byrow=TRUE))

Jim
