X ++ get resourcename from recid

I have highly customized the Project Transaction Report (projlisttransproj and I am showing the resource id). I would like to display the name of this resource instead (see insert method). I am new to x ++ development, so a step by step tutorial would be greatly appreciated. I looked at the projtrans class and found below, but didn't find anything referencing the name ... thanks!

/// <summary>
    /// Retrieves the ID of the employee that is associated with this transaction depending on the
    /// transaction type that is returned by the <c>ProjTrans.transType</c> method.
    /// </summary>
    /// <returns>
    /// The <c>RecID</c> value of the employee that is associated with this transaction.
    /// </returns>
    /// <remarks>
    /// For hour, cost, and revenue transactions, the employee ID will be returned. For all other
    /// transactions, 0 will be returned.
    /// </remarks>
    public ResourceRecId projIdentResource()
    {
        ResourceRecId     resourceRecId;

        switch(this.transType())
        {
            case ProjTransType::Hour:
            case ProjTransType::Cost:
            case ProjTransType::Revenue:
                resourceRecId   = this.resource();
                break;
            default:
                resourceRecId   = 0;
        }

        return resourceRecId;
    }
