我希望能够按位置（纬度）计算以下数据集的平均“IntakeEnergy”。我认为我遇到的问题是数据集同时包含数字和字符，这导致函数不知道如何计算字符串的平均值。我尝试按纬度对数据进行分组，然后使用以下方法计算其他列的平均值：

blah<-profit.fall.all %>% group_by(Lat) %>% summarise_all(funs(mean))

但是，这只有在我删除所有字符串列时才会成功。我对 excel 更加熟悉，我相信一个潜在的解决方案是创建一个数据透视表，但我不确定这是否是解决这个问题的最佳方法。

Data<-dput(head(profit.fall.all,15))
structure(list(Id = structure(c(35L, 70L, 20L, 5L, 15L, 5L, 35L,

与之前的答案相反。

试试summarise_if(is.numeric, mean, na.rm = TRUE)[确定你只想要Lat]

library(dplyr)

我们也可以使用summarise_at

library(dplyr)
profit.fall.all %>%
    group_by(Lat) %>%
    summarise_at(vars(Long,IntakeEnergy), mean, na.rm = TRUE)
