r - Using regex and subset to extract a subset of a data frame -


i have 1 column inside dataframe contains different kinds of text within it, example follows:

column                 column b               column c kuala lumpur 2 new        7                      old jakarta 3             6                      c 7 hong kong               3                      jakarta new 22            2                      b

my goal extract rows of dataframe corresponding word 'jakarta' somewhere in aforementioned column. imagine regex capable of finding word, not sure how 1 combine extract info via subset. note sheet large, prefer use command subset rather loop if possible. desired output be:

column                 column b               column c old jakarta 3             6                      c jakarta new 22            2                      b

many in advance help
