我有一个包含多个变量的数据框:
Subj DashedOrQuest ItemNo TimesOrCorrect
1 dashed 243 859
1 dashed 243 648
1 dashed 243 655
1 dashed 243 389
1 question 243 1
1 dashed 244 465
1 dashed 244 844
1 dashed 244 578
1 dashed 244 713
1 question 244 0
我想要做的是创建一个新的列“Quest”,这样对于每个ItemNo,在DashedOrQuest中,TimesOrCorrect中的数字将为“question”值。换句话说,它应该看起来像这样
Subj DashedOrQuest ItemNo TimesOrCorrect Quest
1 dashed 243 859 1
1 dashed 243 648 1
1 dashed 243 655 1
1 dashed 243 389 1
1 question 243 1 1
1 dashed 244 465 0
1 dashed 244 844 0
1 dashed 244 578 0
1 dashed 244 713 0
1 question 244 0 0
如何在R中做到这一点?提前谢谢!

from django import form
q = models.Person.objects.all()
qty = range(len(q))
PersonForm = type('PersonForm',
(forms.Form,),
{'person'+'_'+str(q[i].id): forms.BooleanField(label=q[i].name,
required=False) for i in qty})

我们可以使用window.onload = function() {
var getpicture = localStorage.getItem('imageData');
var image = document.createElement('img');
image.src = getpicture;
};
data.table
