合并矩阵时，出现没有适用于"c('matrix', 'character')"目标对象的方法的错误

yezi-ss

比如

e

row. names wushu lush jiuliu

sw 1 5 6

de 3 3 6

fr 4 5 6

gt 4 6 3

hy 3 5 12

ju 13 34 56

ji 12 34 43

f

row. names sample size tie

de Nada as tf

hy as Ed fs

gt as ft df

现在想要的就是从e矩阵中重新构建出只有de,hy,gt列名的三行矩阵，行名不变。（de,hy,gt来源于f矩阵）然后运行
g=dplyr::inner_join(f,e,by =row.names)
Error in UseMethod("tbl_vars") :
"tbl_vars"没有适用于"c('matrix', 'character')"目标对象的方法
运行g=merge(f,e,by =row.names)
Error in as.vector(x,mode):
cannot coerce type ‘closure’to vector of type 'any'

tctcab

e=data.table::fread(
"row.names wushu lush jiuliu
sw 1 5 6
de 3 3 6
fr 4 5 6
gt 4 6 3
hy 3 5 12
ju 13 34 56
ji 12 34 43"
)

f=data.table::fread(
"
row.names sample size tie
de Nada as tf
hy as Ed fs
gt as ft df
"
)

library(dplyr)

g= f %>% 
  left_join(e)
#> Joining, by = "row.names"

g
#>   row.names sample size tie wushu lush jiuliu
#> 1        de   Nada   as  tf     3    3      6
#> 2        hy     as   Ed  fs     3    5     12
#> 3        gt     as   ft  df     4    6      3
