我试图在R中获得一个类似于Stata 的2路表.我试图CrossTable从gmodels包中使用,但表不一样.你知道如何在R中完成这项工作吗？

我希望至少能从中得到频率

当cursmoke1 =="是"&cursmoke2 =="否"并反转

在R中,我只能从是,否和NA获得总数.

这是输出:

塔塔

. tabulate cursmoke1 cursmoke2, cell column miss row


+-------------------+
| Key               |
|-------------------|
|     frequency     |
|  row percentage   |
| column percentage |
|  cell percentage  |

   smoker, |      Current smoker, exam 2
    exam 1 |        No        Yes          . |     Total

我正在使用报告实验室,我无法通过platypus添加png图像这是一些示例代码来自http://www.tylerlesmann.com/2009/jan/28/writing-pdfs-python-添加图像/,附加错误,用于追加png

你能帮我搞定吗？

#!/usr/bin/env python

import os
import urllib2
from reportlab.lib.pagesizes import letter
from reportlab.platypus import SimpleDocTemplate, Image

filename = './python-logo.png'

def get_python_image():
    """ Get a python logo image for this example """
    if not os.path.exists(filename):
        response = urllib2.urlopen(

        f = open(filename, 'w')
        f.write(response.read())
        f.close()

get_python_image()
