r - plotting 2 curves; solid lines instead of dotted -


i plot 2 functions in graph. 

r <- rnorm(20,0,1) z <- c(1,1,1,1,1,-1,-1,-1,1,-1,1,1,1,-1,1,1,-1,-1,1,-1) data <- as.data.frame(na.omit(cbind(z, r))) series1 <- ts(cumsum(c(1,data[,2]*data[,1]))) series2 <- ts(cumsum(c(1,data[,2])))

the plot of series2 looks this. enter image description here

combining 2 curves in 1 graph 

matplot(cbind(series1, series2), xaxt = "n", xlab = "time", ylab = "value", col = 1:3, ann = false, type = 'l')

gives this:

enter image description here

the curve of series2 dotted line.

i have 2 questions:

1) how can change dotted line solid line?

2) titles axis not shown in either of graphs. how can fix that?

thanks in advance.

the code below should give desired results:

matplot(cbind(series1, series2), xaxt = "n", xlab = "time",          ylab = "value", col = 1:3, ann = true, type = 'l',          lty = 1)

lines

the key options are:

  • ann = true
  • type = 'l'
