我试图在一组数字上使用聚合函数。在聚合完成计算我想要的功能后，我将输出写入csv文件。但是这个CSV文件包含一个值表和一个计数表。我想删除计数表。我查了一下 聚合的小插图和整个{STATS}手册。但找不到一个能为我做这个的参数。
所以问题是：如何告诉聚合我只想要值列而不是计数？
我写的聚合函数：
sdint<-aggregate(assayData(object)$intensity[,sample],
by = list(assayData(object)$states[,sample]),
sd,
na.rm=TRUE)
我正在使用的数据： Data
我想要的输出：

0.339285757
