Question

我有一个如下所述的矢量：

("#99" "Hershey" "$6.7 B" "7%" "$4.7 B" "$562 M" "Consumer Packaged Goods"
 "#100" "Costco" "$6.7 B" "14%" "$117.3 B"  "-"  "Retail")

为简单起见，我只提到了700个元素中的少数元素。

我想将其转换为数据框，如下所示：

S.NO  Brand Brandval Change Revenue  Cost   Industry
99  Hershey $6.7 B    7%     $4.7 B  $562M   Consumer Packaged goods
100 Costco  $6.7B     14%    $117.3B  -     Retail

我正在尝试使用as.data.frame，但它会在一列中提供结果，而我想将其拆分为7列，如上所述。请帮忙。

您可以这样做：根据重复1:7的向量拆分向量，然后应用cbind.data.frame。最后，添加列名

x=c("#99", "Hershey", "$6.7 B", "7%", "$4.7 B", "$562 M", "Consumer Packaged Goods", "#100", "Costco", "$6.7 B", "14%", "$117.3 B",  "-",  "Retail")
res <- cbind.data.frame(split(x, rep(1:7, times=length(x)/7)), stringsAsFactors=F)
names(res) <- c("S.NO", "Brand", "Brandval", "Change", "Revenue", "Cost", "Industry")
str(res)
#### 'data.frame':  2 obs. of  7 variables:
####   $ S.NO    : chr  "#99" "#100"
####   $ Brand   : chr  "Hershey" "Costco"
#### ...

您可以选择StringAsFactors选项，以便获得字符或系数列

将矢量转换为具有多列的数据帧
