R：循环合并数据帧并cbind这些

我有一个像[] R: merge unequal dataframes and replace missing rows with 0这样的问题

以下是此问题的数据：

df1 = data.frame(x=c('a', 'b', 'c', 'd', 'e'))
df2 = data.frame(x=c('a', 'b', 'c'),y = c(0,1,0)) 
df3 = data.frame(x=c('a', 'b', 'c', 'd'),y = c(1,1,1,0))
df4 = data.frame(x=c('b', 'a', 'e'),y = c(0,1,0))
zz <- merge(df1, df2, all = TRUE)
zz[is.na(zz)] <- 0

在这个例子中，我将df1与df2合并 . 现在我想创建一个循环来合并df3和df4以及更多数据帧与df1 . 问题是列表中的结果必须是cbind才能生成最终的数据帧 .

谁能帮我？

谢谢！

编辑！这是我创建的循环 . 变量goterms禁止包含10个变量的列表 . 变量是interestGO中列表的名称 . 选择第一个感兴趣的GO，计算结果是变量结果 . 此结果必须与x合并 . 因为它是一个循环，所有10个结果必须是cbind才能创建最终的数据帧 .

for (i in 1:length(goterms)){
  goilmn<-as.data.frame(interestedGO[i])
  resultILMN<-match(goilmn[,1], rownames(xx2),nomatch=0)
  resultILMN[resultILMN] <- 1
  result<-cbind(goilmn,resultILMN)
  colnames(result) <- c('x','result')

  zz<-merge(x, result, all=TRUE)
  resultloop<-zz[is.na(zz)]<-0
  standard[i]<-cbind(resultloop)
}
