sed question

I have created a text file that contains two lines- one with a timestamp,
the other with one ping command output. I want to join both lines (remove
the linefeed after the first line), but am having no luck. I open the file
in vi, and attempt to use the following:
        :1,$s/1998\n/1998/ <<1998 is the last token in the line>>
Any help is appreciated
