如何呈现好看的效果?

我想为自己的功能展示一个漂亮的外观。

我创建了自己的函数来解决一些卡方测试练习,结果如下:

enter image description here

这是我自己的功能:

chisq.poly = function(prob, freq, significance.level = 0.95) {

  #calculate chi-squared value
  expect_freq<-prob*sum(freq)
  dif_freq<-freq-expect_freq
  dif_freq_sq<-((freq-expect_freq)^2)/expect_freq
  chi_square<-sum(dif_freq_sq)
  chi_square_crit<-qchisq(significance.level, length(freq)-1, lower.tail=TRUE)

  #we put all necessary values into a dataframe (good for display) and then rename headers
  chi_table<-data.frame(prob,freq,expect_freq,dif_freq)
  colnames(chi_table)<-c("Probability","Frequency","Expected frequency","Difference")

  #Finally, we show the result of test
  hypothesis<-"H0: The experimental data is like the statemnent."
  result<-if (chi_square>chi_square_crit) {"Reject the null hypothesis. The experimental data is not like the statemnent."
  }
  else "cannot reject null hypothesis"

  warning_test<-if (abs(sum(expect_freq-freq))<sum(abs(expect_freq-freq))) {"The expected frequency value may be less than 5, the result cannot be properly."
  }
  else "Something good so far."

  O<-list(chi_table,chi_square,chi_square_crit,hypothesis,result,warning_test)

  names(O)<-c('Table','Chi_square','Critical Chi_square','Hypothesis','Result','Warning')

  return(O)
}

我想像这样或更佳地解决它:
