Is this what you want:

a<- "12345_mydata"
sub("_.*", "", a)

[1] "12345"

Hi,

here im unable to run a string handle function called unpaste().

for eg:- a<- "12345_mydata"
Actually my requirement what is i need to get , only 12345.  Means that , i
need the all letter as a word which is before of  first  " _ " - symbol of
"a". i tried to do with unpaste, it says function not found.  After that i
tried with "strsplit() ". it ran, but again i need to write another method
to get again after spliting.

Any other good method is there for this requirement ?

- Thanks
Antony.
