Hi All,
Sorry for one basic question. My vector contains two class of group
elements,  shown in different font and color
x=c(*1.1, 1.2, 1.3*, 2.1, 2.2)
I am trying to group the objects into two classes, as *1.1, 1.2, 1.3* and
2.1, 2.2

I can use command
grep("^1.[12345678910]",x)
[1] 1 2 3

> grep("^2.[12345678910]",x)
[1] 4 5

but I am not able to automate it, using some variable k.
I have many such cases, so I want to write a iterative loop for the
structure using some variable k,
for test case, lets assume

k=1
grep("^k.[12345678910]",x)
integer(0)


Thanks in advance.

Alok
