我必须从表中删除重复的行（行基于“名称”列），但仍将具有最高值的行保留在“ dist”列中。
我尝试使用：
table_having_duplicates[!duplicated(table_having_duplicates$name), ]
但它会删除所有内容
这是示例数据集：
table_having_duplicates <- data.frame(name = c("OP2645ii_d","OP5048___g","OP5046___e", "OP5048___g", "OP2413iiia", "OP5048___g", "OP5043___b", "OP5048___g", "OP3088i___a", "OP5048___g", "OP5046___a", "OP5048___g", "OP5048___b", "OP5048___g", "OP5043___a", "OP5048___g", "OP2645ii_d", "OP5048___g", "OP2645ii_d", "OP5044___c", "OP2413iiib", "OP5048___g", "OP5046___c", "OP5048___g"), gr = c("gr3","gr2","gr5", "gr2", "gr1", "gr2", "gr1", "gr2", "gr1", "gr2", "gr5", "gr2", "gr5", "gr2", "gr3", "gr2", "gr3", "gr2", "gr3", "gr2", "gr4", "gr2", "gr1", "gr2"), dist = c(7.590363,7.590363,6.449676,6.449676,6.419955,6.419955,6.349918,6.349918,6.182623,6.182623,6.162655,6.162655,6.154232,6.154232,6.140147,6.140147,6.058633,6.058633,5.962923,5.962923,5.943956,5.943956,5.863753,5.863753))
我想要一个没有重复项的干净表，以使每个“名称”的值保持最高。
