Code:
$more file9
id_1 phase1
id_1 phase2
id_1 phase3
id_2 phase1
id_2 phase2

$awk '
{
          if (vector[$1])
              vector[$1]=vector[$1]","$2
      else
              vector[$1]=$2
}
END {
        for (palabra in vector)
                print palabra" "vector[palabra]
}       
' file9

Result:
id_1 phase1,phase2,phase3
id_2 phase1,phase2

mlib_VectorAng_U8C(3MLIB)				    mediaLib Library Functions					 mlib_VectorAng_U8C(3MLIB)

NAME

       mlib_VectorAng_U8C, mlib_VectorAng_S8C, mlib_VectorAng_S16C, mlib_VectorAng_S32C - vector complex phase (angle)

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_VectorAng_U8C(mlib_d64 *a,
	    const mlib_u8 *x, mlib_s32 n);

       mlib_status mlib_VectorAng_S8C(mlib_d64 *a,
	    const mlib_s8 *x, mlib_s32 n);

       mlib_status mlib_VectorAng_S16C(mlib_d64 *a,
	    const mlib_s16 *x, mlib_s32 n);

       mlib_status mlib_VectorAng_S32C(mlib_d64 *a,
	    const mlib_s32 *x, mlib_s32 n);

DESCRIPTION

       Each of these functions computes the phase vector of a complex vector.

       The following equation is used:

	 a[i] = atan(x[2*i + 1] / x[2*i])

       where i = 0, 1, ..., (n - 1).

PARAMETERS

       Each of the functions takes the following arguments:

       a    Pointer to the destination phase vector.

       x    Pointer to the source vector

       n    Number of elements in the vector.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
