R：gsub，模式=向量，替换=向量

如标题所示，我尝试使用gsub，其中将向量用于“样式”和“替换”。目前，我有一个代码如下：

  names(x1) <- gsub("2110027599", "Inv1", names(x1)) #x1 is a data frame
  names(x1) <- gsub("2110025622", "Inv2", names(x1))
  names(x1) <- gsub("2110028045", "Inv3", names(x1))
  names(x1) <- gsub("2110034716", "Inv4", names(x1))
  names(x1) <- gsub("2110069349", "Inv5", names(x1))
  names(x1) <- gsub("2110023264", "Inv6", names(x1))

我希望做的是这样的：

  a <- c("2110027599","2110025622","2110028045","2110034716", "2110069349", "2110023264")
  b <- c("Inv1","Inv2","Inv3","Inv4","Inv5","Inv6")
  names(x1) <- gsub(a,b,names(x1))

我猜想某个地方有一个Apply函数可以做到这一点，但我不确定要使用哪个函数！

编辑：名称（x1）看起来像这样（还有更多列，但我将其省略了）：
