Loop on characters

megh -
    The best way to organize similar objects in R is to
put them into a list.  If you keep this in mind when you're
first organizing your data, it's no harder than giving each object
a separate name.  For example

l = list(l1,l2,l3)

The reason that this is a good idea in R is that functions
like sapply, lapply, and mapply automatically operate on each
element of a list, and return the answer in a suitable R object. 
(Note that in your example, you would get an error because you 
hadn't defined count1.  And why should you?)

So the answer you want is

count1 = sapply(l,length)
count1

[1]  4  6 52

Hope this helps.

Hi,

suppose I have three vectors like :

l1 = 1:4
l2 = 4:9
l3 = 16:67

now I want to construct a loop like :

for (i in 1:3)
  {
    count1[i] = length(li) # i.e. it will take l1, l2, l3 according to
value of i
  }

Can anyone please tell me how to do that?

Regards,
