我有一个dataframe列表，它们都具有相同的列结构（参见下面的数据的可重复部分）。
列表中的元素目前是用数字命名的，而我想根据Contrast列的值来命名它们。

list(`1` = structure(list(gene_name = c("EGR1", "FOS", "DUSP6", 
"MTND2P12", "PRKG1"), logFC = c(1.76654254980119, 1.17127823620834,

我试着用下面的代码来做这件事，但它只返回每个元素的名称和对比的名称。

lapply(seq_along(DEGs_list), function(i) (names(DEGs_list)[[i]] <- DEGs_list[[i]]$Contrast[1] ))

任何帮助将不胜感激！
