读取具有两行标题的文件[重复](Reading in files with two rows for header [duplicate])

问题

我一直在使用SurveyGizmo,它可以将数据导出为CSV文件,但是可惜它有两行用于标题。 第一行指定问题,第二行包含受访者可能已经核对的可能答案。 在数据读写世界中,这似乎是异常的,但在调查领域中,这似乎是很正常的。 如何将这样的文件读入R?

SurveyGizmo曾经有一种“旧的”导出格式,将所有内容都排成一排,但是似乎公司不再支持它了。 在一次简单的调查中,一位正在帮助我的实习生能够使用以下代码克服了这个问题。 但是,对于具有更多问题的更长调查,以及问题更长(因此标题也更长),我们上面的蛮力方法不起作用。

#Read csv file with two rows of headers
#Append the second row to the first row
df <-read.csv(csvfile,skip=1,stringsAsFactors=FALSE) #Read csv without any header
hl=readLines(csvfile, 2)            #Read the two header lines as char strings
hl=strsplit(hl,',')                   #Split headers up by commas
colnames(df)=sub('_$','',paste(hl[[1]],hl[[2]],sep=""))  #join second row to first row  

最后,我想要一个带有列标题的数据框,然后将其与来自后续调查的另一个数据框合并。

这是带有两个标题行的CSV文件的示例。 第三行也是最后一行是数据的第一行(不是真实信息)。

为什么不只将read.csv读入第一行标题(我理解您的问题就是实际的标题),然后跳过下一行:

read.csv(file, header=T, skip=1)

或者,如果第二个标题行以特殊字符开头(在数据中找不到),则可以通过将以该行开头的字符作为参数comment.char的值传入,来将该行指定为注释行(如果那行以“#”开头,​​例如)::

read.csv(file, header=T, comment.char="#")

实际上,我认为最简单的方法是使用SurveyGizmo SPSS导出。 将数据导出到SPSS,然后在R中使用类似的命令来:

read.spss(file='mydata.sav')

实际上,这应该对您来说完美无缺,并将所有数据描述也带入R中。

在第3版中,当前处于活动状态的“快速导出”是单列导出,并将保持这种状态-受到官方支持。

遗憾的是,此导出文件的较旧版本已被删除,并且未进行优化,因此无法对其进行升级以与某些更现代的浏览器一起使用。 特别是因为新的出口距离接管仅几周时间。

在这种情况下,SPSS导出是必经之路!
