Re: [R] plotting several columns of matrix in one graph

HI, It is better to show a reproducible example using ?dput().  May be this helps: #vector vec1 <- seq(as.Date("2002-01-01"), as.Date("2009-12-31"),by="1 day") #Assuming that length of the vector is the same as ?nrow of matrix. set.seed(532) mat1 <- matrix(cumsum(rnorm(length(vec1)*5)),ncol=5, d
