Manipulate Chart Select Multiple Time-Series

I have created the plot below, so that I can easily compare multiple timeseries over different sections of time. I would next like to add a selector so that I can pick multiple timeseries to view on the plot at the same time, and uncheck the ones I don't want to see on the plot.

code:

y<-series1
r<-series2
s<-series3

require(graphics)
manipulate( 
ts.plot(ts(y[x:(x+100)]),ts(r[x:(x+100)]),ts(s[x:(x+100)]),ts(t[x:    (x+100)]),ts(h[x:(x+100)]), gpars=list(col = c("red","green","gray")))
 ,  
 x=slider(1,length(y)))

data:

dput(series1[1:10])
c(9.5, 9, 14.5, 22.5, 13, 16, 22, 31.5, 51, 43)


dput(series2[1:10])
c(20.3368220204774, 18.0733372276398, 16.61695493123, 15.6798824136643, 
15.0769466973063, 14.6890028922692, 14.4393902191708, 14.2787832298018, 
14.175444706505, 14.1089541357078)

dput(series3[1:10])
c(17.8189147557743, 22.3815592342001, 16.108169527143, 21.0654757276344, 
16.3878646132368, 18.9345933680916, 16.634277276197, 15.4322081636797, 
20.2884280389731, 12.2089595405668)

Solution

You could do it like this

y<-c(9.5, 9, 14.5, 22.5, 13, 16, 22, 31.5, 51, 43)
r<-c(20, 18, 17, 16, 15, 15, 14, 14, 14, 14)
require(graphics)
require(manipulate)
manipulate({ 
  lines <- list(if (chk.y) ts(y), if(chk.r) ts(r))
  cols <- c(if (chk.y) "red", if (chk.r) "green")
  do.call(ts.plot, c(lines, list(gpars=list(col=cols, xlab="t", ylab="y"))))
}, 
  chk.y=checkbox(TRUE, "y"),
  chk.r=checkbox(TRUE, "r")
)
