计算R矩阵中每列特定整数的数量

def count_specific_integer(matrix, specific_integer):
    num_columns = len(matrix[0])
    counts = [0] * num_columns

    for col in range(num_columns):
        for row in range(len(matrix)):
            if matrix[row][col] == specific_integer:
                counts[col] += 1

    return counts

# 示例数据
R_matrix = [
    [1, 2, 3],
    [4, 5, 6],
    [2, 2, 2],
    [7, 8, 9]
]

specific_integer = 2

result = count_specific_integer(R_matrix, specific_integer)
print(result)
