[R] merging two specific rows in a DF

[karthicklakshman]

Hello members,

I have this data frame with 3 columns,
C1	C2	TYPE
10	20	A
33	44	B
66	80	A
111	140	B
144	220	B
300	340	A
380	449	A
455	500	B
510	520	A
540	580	B

Here,  the rows 4 , 5 has type "B" and similarly 6,7 has "A" . I need to
merge these rows in a way to get the output with unique type, something like
below, where the lowest value from DF$C1 and  highest value from DF$C2
corresponding to rows 4,5 are picked.

C1	C2	TYPE
10	20	A
33	44	B
66	80	A
111	220	B
300	449	A
455	500	B
510	520	A
540	580	B

I Request your kind help..
Regards,
karthick
