[R] Merging files function

[Ahamarshan jn]

hi list,

This question must be very basic but I am just 3 days
old to R, so I think i can ask. I am trying to find a
function to merge two
tables of data in two different files as one.

 Does merge function only fills in colums between two
table where data is missing or is there a way that
merge can be used to merge data between two matrixes
with common dimensions.

say i have

   v1 v2 v3 v4   
h1
h2
h3
h4
h5

and and another table with 

   x1 x2 x3 x4
h1
h2
h3
h4
h5


can i merge the data as

   v1 x1 v2 x2 v3 x3 v4 x4
h1
h2
h3
h4
h5

Thanks
