[R] split character vector by multiple keywords simultaneously

[Greg Snow]

Will all the keywords always be present in the same order?  Or are you looking for the keywords, but some may be absent or in different orders?

Look into the gsubfn package for some tools that could help.

Subject: [R] split character vector by multiple keywords simultaneously

Hi. I have a character vector that looks like this:

> temp <- c("Company name: The first company General Manager: John Doe I
> Managers: John Doe II, John Doe III","Company name: The second company
> General Manager: Jane Doe I","Company name: The third company Managers:
> Jane Doe II, Jane Doe III")
> temp
[1] "Company name: The first company General Manager: John Doe I Managers:
John Doe II, John Doe III"
[2] "Company name: The second company General Manager: Jane Doe I"                                   
[3] "Company name: The third company Managers: Jane Doe II, Jane Doe III" 

I know all the keywords, i.e. "Company name:", "General Manager:",
"Managers:" etc. I'm looking for a way to split this character vector into
multiple character vectors, with one column for each keyword and the
corresponding values for each, i.e.

        Company name          General Manager                  Managers
1  The first company            John Doe I                John Doe II, John
Doe III
2 The second company        Jane Doe I                          
3  The third company                                          Jane Doe II,
Jane Doe III

I have tried a lot to find something suitable but haven't so far. Any help
will be greatly appreciated. I am running R-2.12.1 on x86_64 linux.

Thanks.
