[R] Extract part of string

[arun]

Hi,
You could try:
sub(".*(ron)", "\\1", 'my name is ron')
#[1] "ron"
#or

 sub('^.* ([[:alnum:]]+)$', '\\1','my name is ron')
#[1] "ron"
A.K.

Hi,

I am struggling to extract a part of string using regular expression in R.

Let say, the string to be extracted is 'ron' from the expression 'my name is ron'. So I tried following:

> gsub("[^(ron)]", "", 'my name is ron')
[1] "nron"


I was expecting to get 'ron', which is not the case.

Could someone please guide me what will be the right way for that?

Thanks for your help.
