[R-SIG-Finance] hist from a data frame that is a list

[Pedro páramo]

Hi all,

I have made some calculus and creating this:


bwfinal <- matrix(bestworst, nrow =35 , ncol = 1)
bwfinal2 <- matrix(namebw, nrow =35 , ncol = 1)

bwc<-cbind(bwfinal2,bwfinal)
colnames(bwc)=c("Accion","reval")
bwc <- as.data.frame(bwc)
colnames(bwchist)=c("Accion","reval")
bwchist <-as.data.frame(bwc[order(bwc$reval), ])

It is supposed thar bwchist is a data frame but when I try to make an hist
it says me

Error in hist.default(bwchist) : 'x' must be numeric

It looks like bwchist is a list but dont I have tried to use unnlist but
always appears the same error

My bwchist is like this when run on the command line How should I treat
this data frame to hist Accio on x axis and values of reval on Y axis?:
