Dear all,
I am stuck at applying loop function for creating separated plots.
I have coding like below:
dataset.table <-
table(data.frame(var1=c(1,2,3,1,2,3,1),colour=c("a","b","c","c","a","b","b")
))
kk = function(f)
{
ls=as.character(f)
pie(dataset.table[ls,],main=ls)
box()
}
kk(1)
kk(2)
kk(3)
By using above code, I can create 3 single plot respectively, but when I
type kk(1:3), obviously it will not work.
I know I have to vectorise the coding, then I can use command kk(1:3). I try
to use loop:
kk = function(f)
{
ls=as.character(f)
for (i in length(f))
{
pie(dataset.table[ls[i],],main=ls[i])
box()
}
}
kk(1:3)
the above code only gives me the last pie plot (ie. kk(3) plot) instead of 3
plots respectively.
Can someone please guide me how to revise the loop coding, and produce 3
separated plots one after another on the screen by typing kk(1:3)?
Thanks a lot.
Rene.
