Question

我正在使用R通过“ tidycensus”提取人口普查数据，但是它将同一地理位置的不同变量拉到行中，而不是使用单行地理位置和多个变量列。

我尝试了各种转置，聚集和扩展功能，但是无法将扩展值折叠到单行中。我的代码如下：

Median_Inc<-get_acs(geography="County Subdivision",table=B06011,state="MA",county="Middlesex","Essex","Suffolk","Plymouth","Norfolk","Worcester")

会生成一个表：

2500901260  Amesbury Town city, Essex County, Massachusetts B06011_001  37891
2500901260  Amesbury Town city, Essex County, Massachusetts B06011_002  37402
2500901260  Amesbury Town city, Essex County, Massachusetts B06011_003  47925
2500901260  Amesbury Town city, Essex County, Massachusetts B06011_004  NA
2500901260  Amesbury Town city, Essex County, Massachusetts B06011_005  27303

我希望得到这些结果，但是我想做的是生成一个表，该表的所有值都包含一行，并且其中的列是变量名，例如：

GEOID   NAME    B06011_001  B06011_002  B06011_003  B06011_004  B06011_005
2500901260  Amesbury Town city, Essex County, Massachusetts 37891   37402   47925   NA  27303

Answer 1

我没有更改get_acs函数，但是只需很少的操作，就可以拥有想要的东西。

名为tab的原始数据：

         Num                 City        County          State        Code   value
1 2500901260   Amesbury Town city  Essex County  Massachusetts  B06011_001   37891
2 2500901260   Amesbury Town city  Essex County  Massachusetts  B06011_002   37402
3 2500901260   Amesbury Town city  Essex County  Massachusetts  B06011_003   47925
4 2500901260   Amesbury Town city  Essex County  Massachusetts  B06011_004      NA
5 2500901260   Amesbury Town city  Essex County  Massachusetts  B06011_005   27303

要具有列名：

colnames(tab) <- c("Num", "City", "County", "State", "Code", "value")

操作后：

library(reshape2)
data_wide <- dcast(tab, Num + City + County + State ~ Code, value.var="value")

     Num                 City        County          State  B06011_001  B06011_002  B06011_003  B06011_004  B06011_005
1 2500901260   Amesbury Town city  Essex County  Massachusetts       37891       37402       47925          NA       27303

折叠命名行并将变量移动到R中的列
