I have read a CSV file into an R data.frame. Some of the rows have the same element in one of the columns. I would like to remove rows that are duplicates in that column. For example:
platform_external_dbus 202 16 google 1
platform_external_dbus 202 16 space-ghost.verbum 1
platform_external_dbus 202 16 localhost 1
platform_external_dbus 202 16 users.sourceforge 8
platform_external_dbus 202 16 hughsie 1
I would like only one of these rows since the others have the same data in the first column.
