请问没有complete cases怎么办啊,> install.packages("copmlete.cases") 显示:
Warning in install.packages :
package ‘copmlete.cases’ is not available for this version of R
您好,请问我的summary函数中为什么没有频数统计呢
Name Region Price
Length:9 Length:9 Min. :1.300
Class :character Class :character 1st Qu.:1.700
Mode :character Mode :character Median :2.500
> t1 -mutate(example1.complete,Total=Price*Kilogram)
Error in mutate(example1.complete, Total = Price * Kilogram) :
could not find function "mutate"
不只是怎么回事,Rtudio版本太高了吗?
