I need to create a data frame “s”, which contains only numbers
and I don’t know how to call “b” to return just numbers. Could you help me to do this?

Answer 1

Not sure if this is a real issue. b indeed contains just the numbers. The words you are seeing are the row names. A small modification of the example you give shows the creation of a data frame with two columns:

library("PerformanceAnalytics")
a<-seq(from=1,to=2,by=.01)
b<-table.Stats(a)
c<-seq(from=5,to=6,by=.01)
d<-table.Stats(c)
e <- cbind(b,d)
str(e)
