我有两个数据帧，我存储为ca13和ca0112。我想使用合并函数按列名合并这两个数据帧。但是，列名称不同。

我试图使用for循环来实现这一点

cnam0112 <- c(names(ca0112))
cname13 <- c(names(ca13))

for( i in 1:size ) { ca13 <- rename(ca13, cname13[i] = cnam0112[i]) }

我得到了通常的错误Error: unexpected '=' in "for( i in 1:16) { ca13 <- rename(ca13, stuff13[i]="

我究竟做错了什么？单独命名每个列名称非常耗时！我只是使用dplyr库。列名是在一个数据帧中具有空格的字符串。作为另一个的分隔符。

[1] "State"                     "Year"                      "Cause"
 [4] "Male.upto.14.years"        "Male.15.29.years"          "Male.30.44.years"
 [7] "Male.45.59.years"          "Male.60.years.and.above"   "Total.Male"
[10] "Female.upto.14.years"      "Female.15.29.years"        "Female.30.44.years"
[13] "Female.45.59.years"        "Female.60.years.and.above" "Total.Female"
[16] "Grand.Total"

[1] "State"                     "Year"                      "Cause"
 [4] "Male upto 14 years"        "Male 15-29 years"          "Male 30-44 years"
 [7] "Male 45-59 years"          "Male 60 years and above"   "Total Male"
[10] "Female upto 14 years"      "Female 15-29 years"        "Female 30-44 years"
[13] "Female 45-59 years"        "Female 60 years and above" "Total Female"
[16] "Grand Total"

Answer 1

我建议你在两个数据帧上使用janitor :: clean_names来获得更清晰，更容易阅读的名称。空格和点由下划线替换，每个列名称都设置为小写。然后名称应该匹配。

Answer 2

我可以使用而不是使用循环

ca13 <- setNames(ca13, names(ca0112))
