Hi All,
I have a character vector by name tickers
> head(tickers,10)
V1
1 ADARSHPL.BO
2 AGR.V
3 AGU
4 AGU.TO
5 AIMCO.BO
6 ALUFLUOR.BO
7 AMZ.V
8 AVD
9 ANILPROD.BO
10 ARIES.BO
I would like to extract all elements that has ".BO" in it. I tried
> grep("\.BO",tickers)
Error: '\.' is an unrecognized escape in character string starting "\."
> grep(".BO",tickers)
[1] 1
Could any one please guide me on this. Many thanks for the help
Best Regards,
Krishna
